Romelu Lukaku is set to make his first appearance since returning to Everton in the friendly against SC Paderborn.
Lukaku completed a Club-record £28million permanent switch to the Blues this week and will be presented to fans at Sunday’s game against FC Porto at Goodison.
But he will not play until the final pre-season game in Germany on 9 August - a match which can be seen live on evertontv.
“He wants to be at Leon Osman’s testimonial on Sunday and he’ll be presented to our fans," said Martinez. "He doesn’t want to miss that occasion.
“But he’ll be back in full training on August 7, the same as Kevin Mirallas after their time at the World Cup. We’ll then see him back playing in a game before the start of the season.”
