He's a good squad player for the future. Something along the lines of Danny Murphy, although I think Guthrie has the potential of becoming the better player. No reason to sell unless the bids are £6-7 million.
I really don't get those who think that Mascherano currently is a better player than Xabi. £20 million? He'll have to prove a lot before Rafa should even consider paying that much.
Liverpool were turned down by two spanish goalkeepers (one chose Real Madrid, the other chose to stay at Barcelona). 16-17 year old players. The deal for Preston Edwards (Millwall) is said to be at an advanced stage though.
I've never seen Malouda dominate or turn a match. He's a decent team player with no real strengths, and he'll fail miserably for Chelski. Robben is much, much better, as is Babel (though not really a winger by trade).
They won't sell a lot of players, but there are three youngsters who could be possible to sign. Djorou, Gilbert and Traoré. Gilbert is more suited for a club such as Everton, but the other two would be good squad players.
