No. The club doesn't think his current salary is reasonable considering his role. It wouldn't make any sense for him to ask for a pay rise at this time whatsoever.
If Vidal is a card magnet like he seems to be in Germany and with Pirlo being injury prone we could end up starting games with a Midfield paring of Pazienza and Marchisio
Melo wouldn't add anything extra in terms of creativity if that's you logic. Back-Ups are Back-ups, at our level we can't have WC bench players, that'd take a few year of constant CL
So Vidal despite being an unknown quantity in Italy can fetch 4m in salary, but our best midfielder last year is undeserving of 3.5? WTF. Sad story that is Juventus.
