Mohamed Salah will deliver the goods for Chelsea by next season, predicts manager Jose Mourinho.

"You know, playing at Stamford Bridge is not the same as playing for FC Basel," Mourinho told French newspaper Le Matin.

"With Basel you play to you enjoy your time and you have nothing to lose. While in the blue shirt, you have 40,000 people that you are required to please. Everyone wants you to be decisive, all the time.

"So I think Mohamed needs six months to adapt our game and the demands of the Premier League.

"I am calm and I’m telling him that he has time because we have confidence in him. I think next season is Mohamed Salah’s break-through season."

Salah made three appearances for Chelsea so far, all of which came from the bench.
