Maybe Andy wont like it, but i never saw a world class in Tiago and he'll never be the team's leader and midfield general. Tiago is a very good squad player who is very reliable and does his duties on the pitch, but we simply can't expect from Tiago to be the one who'll make the team play better.
I like him, i like to have him in my team, but with the players we have around him we're forced to rely on Tiago to be the only one who'll create our game and Tiago isn't the man for the job. He's creative player but not THE one who should do all the job in creating chances.
In Lyon he had Juninho who was giving the creative spark , in Portugal he has Cristiano Ronaldo and Deco, in Chelsea he had Joe Cole, Lampard, Robben. And he worked pretty well there, when he had all the class around him.
With us, when Camoranesi is out, he has Nocerino, Zanetti and Nedved stuck on the left line of the pitch, and sometimes he has Salihamidzic there. He's alone and he's not the player who can do the things we expect him to do when he doesn't have another similar player with him on the pitch.
And looking at how the other teams threated him, one may ask himself if he's really the class we thought he is.
Chelsea saw the potential in him and bought him for 15m euro. Then after one single year they sell him for 10m euro. Lyon , the team that always sells their players for double their realistic price sold him to us for 13m euro, when he was 26 and with his best years in front of him, earning only 3m euro on him. Lyon sold Diarra, Essien, Malouda for 20 or 30m euro, they sold even the left back Abidal for 15m euro and now they sell Tiago for much less.
Why ?
To sum up, don't expect miracles from Tiago and lets not sell him but lets buy vdV and get back Giovinco so Tiago will be able to do the job he was doing at Chelsea, Lyon and Portugal. The way it is now Tiago is forced to do the job 2 or 3 men were doing in his previous clubs.
