The Italian has now set his sights firmly on going all the way in the Europa League, but has vowed not to take his focus off the Premier League as he looks to secure a domestic and European double in his second full season at the club.
And when quizzed on the prospect of a twin trophy pursuit, the Citizens manager replied: "We hope so but it is not easy.
"We want to try to go to the final if possible but it will be difficult because the Europa League has top squads – Manchester United, Valencia, Schalke - it is like the Champions League.

"If we go through in the Europa League it will be important to have four strikers."
