It will be interesting to see how the Armenian fares at Roma this season under Jose Mourinho - a manager who didn’t give him many opportunities at Old Trafford.

However, it seems that both the player and the manager want to start “from scratch.”

"Mourinho is very ambitious, he always wants to win. He doesn’t care if we play good or bad football, it’s all about the three points," he told Sky Italia.

"Everyone knows he has won almost everything there is to win.

"I don’t want to talk about the past, we discussed it together and started from scratch on a different level. I know what he asks of his players and I am ready to give my all."
