Think Vidal should go for a surgery if that can completely solve all problems.....He is a beast and playing through pain and giving less than 100% is not what we would desire long term
Happy that we have signed capable bench players who can do the job....Pogba-Marchisio-Asamoah with a backup of Pereyra,Romulo is still in the top 2 midfields in Serie A.When Pirlo returns,we would be nearly full strength again,considering the beast that Pogba is becoming.
A layoff of 2-3 months with the final result being a fully 100% Vidal for another 4-5 years is a gamble I am personally willing to take.
Also,there are some sources claiming it was just a twinge and he would be fit in 2 weeks atmost.
