According to posts on another forum, Levy met with Collocini's agent this week. Agent also represents Gago. Seems more likely we would be looking at Collocini though.
Might just be personal preference, but even though I rate Coloccini, he's at the very bottom end of the 'top Premier League defender' bracket. Kaboul did everything better than him last season across the board, and Vertonghen certainly looks like he'll be better in time. I think Caulker's gonna be immense too. So no place for him in our first team, and I can't imagine him liking that coming off the back of being his former team's best-loved enduring players.
