The Serbian knew the Red Devils were getting a great player in the Portuguese playmaker, but did not think he would make such a rapid impact
Bruno Fernandes' start at Manchester United has shocked Nemanja Matic, who did not expect the Portugal international to adapt to life at Old Trafford so quickly.
United are unbeaten in 18 games across all competitions having been boosted by the arrival of Fernandes from Sporting in January after a lengthy transfer saga.
The midfielder has more than lived up to the hype, scoring seven goals and adding a further seven assists in just 11 Premier League outings.
