I am in my second season with Celtic too, and allmost everyone from the team you show is gone. Just sell them or loan with option to buy. Though keep the scottish players, especially Scott Brown.
Btw. Off topic, what the name on your skin?
Off the bat, you'll need a good keeper. I'd suggest Enyeama, but chances are he's already out of reach.
Defence is another big one, Majstorovic is getting old so look out for agents offering you good young Central defenders to play along side Loovens.
Midfield is good enough, Brown and Ledley play well with each other, maybe play Ki in DMC with Maloney AMC?
Striking is a surprise. Hooper has a good few years in him and so does Stokes, but give Samaras a game or two from time to time.
As for Youngsters, don't touch Atajic or Spence, both of whom will become good SPL players given the right playing time. If you see dead wood, ship them out [especially Cha Du Ri]
Agreed with Berra, not sure about Danny though since his favourite club is Rangers.Go for a good scottish defender like Berra or Danny Wilson
I'm sure i heard Danny Wilson was actually a Celtic fan, not sure though.
On topic agree with most of the above and maybe try and get some loan's from top premiership clubs maybe even with an option to buy if you have the money.
He still isn't going to leave liverpool for celtic though Scott Brown is also a Rangers man, Think Kev Thomp is a Celtic Man too lol think we got the best deal though.
Am sure browns got a rangers tattoo on his leg lol the mad **** he is haha
