NB: I picked two teams because there were some players I really just couldn't leave out. I made several changes to the 2nd one, but that was more to justify making a 2nd team than because all of those positions are actually close 
Without further ado, my explanations:
GK: Hart - Just brilliant. What else is there to say? He's England No. 1 and will be for some time. He and Reina, for me, are the most consistent 'keepers in the league. There are some excellent goalkeepers, but I think those two make the least mistakes and they're always far between, too. Hart pips Reina to the post because I think he's a better shot-stopper, just.
Krul - In there because with a defence like Newcastle's (often makeshift, cavalier and without a huge amount of PL exp.), he always has plenty to do and has given them some vital points against Utd and others almost entirely by himself.
RB: Richards - I don't anyone this season comes close to him in terms of quality. I still think Sagna is just about a better player, but he's not really played this season so I can't include him (I know it's TOTY, but still). Richards' versatility and die-hard attitude make it difficult to deny him this spot. Has the same goals/assists MIDFIELDER
Alex Song this year (1/5) and can do pretty much everything.
Phil Jones and Kyle Walker also deserve a mention.
CB(s): Kompany & Koscielny - There's not much arguing with Kompany's inclusion. He's not just been one of City's best defenders this year, but one of their best players full stop. Beast in the air and a strong tackler to boot, he gives away just 1.1 fouls/game and only allows an opposition player to dribble past him 0.3 times/game.
Koscielny may come as a bit of a surprise to some, particularly those who thought he struggled last season. Firstly, let's not forget that in his first season in the PL, never mind as an Arsenal player, and only his 2nd in a top division, he had to play with 4 different CB partners. His pace and expert positioning is highlighted by his 2.8 interceptions/game and 1.6 offside decisions won/game (second only to Gary Cahill).
Vidic - Hasn't played much this season (Only 6 games) so I gave Koscielny the spot ahead of him, but last season's performances were superb week-in, week-out. His importance to Utd is becoming increasingly clear with their makeshift defence leaking goals.
LB: José Enrique - Most sought-after LB this summer. A bargain for £5m or whatever it was in the end. Pity Arsenal didn't sign him, but he's another player who seems to have perfected the balance between going forward and not letting anyone past him in his own box.
Baines - Decent enough defender, but mainly in the second team to make up numbers and because he adds invaluable goals and assists.
CM(s): Song and Touré - Yaya Touré is just such a magnificent player. I'd love to have a stat for how far he runs every game, because it seems like he never stops. His African background appears to have given him an insane amount of energy, like those Kenyan marathon runners, while his days at Barcelona mean he has plenty of technical quality on the ball (1 successful dribble, 1.3 KP & 0.3 through-balls/game). Mancini's Italian roots have also hepled Touré to improve as a defender (behind only Barry for most tackles/game at City).
Tioté and Modric -The former seems to get booked every game, but his terrier-esque approach to chasing down the ball is one of the main reasons Newcastle have got so many points and good performances against the best passing teams this season (Arsenal x2. Utd x2, Chelsea, etc.). He doesn't give the opposition a moment's peace on the ball.
Modric is another highly sought-after player, and I get the feeling that if Spurs lost him, their CL challenge would be significantly reduced. They have other good players - Bale, Parker, VdV - but Modric makes them tick and can wriggle out of pretty much any situation. Modric, for me, is the complete player.
These two only lose out because a) I'm biased and I love Song and Touré, and b) I prefer the tactical set-up of Team 1 - Silva doesn't track back much so it was important to have two defensive-minded players but who can still go forward when they need to.
"Winger(s)": Bale and Mata - Bale just keeps getting better and better. He's now added assists to his goals, and has become less predictable in his play. Last season, Rafael of Man Utd kept him quiet by ensuring he had to come inside and matched him for pace down the wing but this season, players can't do that any more. The only thing lacking before he really is the next Ryan Giggs is a more varied passing range, completing just 1.6 long-balls/game (only just more than Adebayor!)
Mata is the second-top assister this season and may well turn out to be Arséne Wenger's biggest regret. While we were fannying about trying to sell Fabregas to Barca as quickly as possible, Chelsea were stealing Mata from right under our noses. A simply superb player who - although not a right-winger - can play there because he's that good
Nani - It's pretty difficult to leave out such a skillful and pacey player. Then again, when he behaves like he does when he gets tackled, he loses a lot of neutral support. Too liable to have a strop so Mata comes in instead. I also think Richards would be more able to get forward with Mata there cutting inside than Nani in front of him.
Attacking Midfielder/Second Striker: David Silva - Top assister in the PL this season, he's a wonderful player to watch. Unlike some, he never makes a fuss and is a prettier, more advanced version of Luka Modric. Both similar players, but like a lot of players in my team(s), Silva is versatile and would link up brilliantly with RvP.
Talking of which... Van Persie - Plays the "Second Striker" or "Bergkamp" role, where a lot of people think he should be playing already. Ideally, I want a player who scored 35 goals to play up-front, but he's just as able to play behind the striker and assist more than he does score. 5 assists this season and 2.2 key passes per game are both joint-high statistics for the Arsenal side.
Striker: Demba Ba isn't far behind RvP in terms of goals this season. Both have had their injury problems, but hopefully they can both remain fit for the foreseeable future. Both brilliant players and would combine superbly IMO.
Very little competition here. Rooney has been inconsistent this season and in 2011, Torres has failed completely, and Suárez - IMO - isn't as good as some say. Even without this racism thing, he has been inconsistent and too easily frustrated when things aren't going his way - unlike Ba and RvP, who have scored countless winning goals between them in difficult games.
