‘Mason has a fantastic character and that’s part of his overall package, plus he has the quality on the ball. Intelligent players who are hungry and have that talent and are fantastic to work with, and Mason is exactly that.

‘He’s impressed me even more from pre-season and I believe he can absolutely go to the top if he continues to work hard.’

The Blues were dealt a blow before kick-off at Carrow Road, with the news that Pedro had picked up an injury in the warm-up and was replaced by Ross Barkley. The Spaniard joins N’Golo Kante in the treatment room, with the French midfielder sitting out the win in Norfolk with an ankle injury, and Lampard has said that both players will be assessed ahead of the weekend clash with Sheffield United at Stamford Bridge.

‘Pedro picked up a hamstring injury and we will assess the severity of it over the next couple of days, but I think it will be tough for him to be back for next week at first glance,’ said Lampard.

‘We obviously then have the international break, so that might help, but we will be trying to get him back as quickly as possible because he’s an important player.
