Would you keep Alonso or sell him and replace him with Nasri?

Inter have offered me £15mil for Xabi Alonso, and i could get Nasri for that. I know that Alonso is DM wheras Nasri is AM but i have;

Mascherano

Sissoko

Gerrard

Modric

Lucas

all can play centre mid

I use a defensive mid(normally Mascherano)

a centre mid (Alonso or Sissoko)

and an attacking mid (would be Gerrard but Modric because Gerrard is supended)

If i signed nasri i could easily push Gerrard back to CM and slot Nasri to AM.

So would you keep Alonso or sell and get Nasri?

Or maybe you would sign a better midfielder than Nasri(also been looking at Michael Johnson)?

Or maybe you think i don't need another central midfielder and wouldn't sign one at all?

If thats the case where would you look to strengten my Liverpool team(sold nobody, only signed Modric and Menez)?

Your suggestions on a postcard please

Probably best to ask in the good players forum because those guys will know who's good and who's not. Also it should be a personal choice because players differ from game to game, I bought Huntelaar on the basis of recommendation on here and he was god awful for me.

Well i often sign Nasri and he always starts the season as quality but fades away. I also think the defence could do with some improvements

Like I said, it's up to you. Some people sign players based on PA whereas I sign on attributes, so i'm sure people would look at my team and think I was mad picking the starting 11 I have compared to the starting 11 I could have.

How do you manage with all the other decisions a football manager has to make if you can't even make a fundamental decision like who to sell and who to sign?!
