Deulofeu has impressed Martinez in his short spells on the pitch for the Blues so far this season, and could be rewarded in Everton’s biggest game so far this season.
“It has surprised me how quickly he has adapted to the British game, and to the demands of the Premier League,” explained Martinez.
“He is fighting hard for his place.
“I would have no concerns about putting him in against Liverpool, no. When you are able to play against Jan Vertonghen, and to cope with that, then it shows you he is ready for anything.”
