I personally can't see us winning the league for 2/3 seasons, as Dobcheev said we'll need a decent amount of cash injected into the club and transfer budget before we'll make a strong challenge, the bottom line is, our squad isn't good enough to compete with United or City over the course of the season, they have the ability to play a completely different team week in, week out and still be favorites to win a game, and they can scrap results out when having a bad game, we can't sadly the majority of the time, hence the amount of draws we've had over the past 2/3 seasons being pretty high.
We need a new Striker, we currently only have Suarez who even has the ability to get beyond 20/25 goals in a season, I doubt Carroll will this season, maybe he'll come close next season, but he needs time to settle into our style of play, I think anyway.
