Anton Donkor has returned to Everton for a second loan spell until January 2018.
The 19-year-old forward joins David Unsworth's title-winning Under-23s team from German Bundesliga club Wolfsburg.
"I'm very happy to be back," Donkor said. "I'm looking forward to pre-season to show my teammates and the fans that it was the right decision for the Club to re-sign me.
"I started very well here last season but the ankle injury was a big disappointment. I was out for about eight weeks and I had to go back to Germany and do all my treatment.
"But I got fit again quickly and now I'm feeling better than before. I'm feeling at 100 per cent."
Donkor has been training with the Under-23s at Finch Farm during the first week of pre-season.
"Training so far has been very good and tough," he added. "After six weeks I hadn't played football, but I was very happy to be back out on the pitch. David Unsworth is a great guy and I enjoy training with him. He has a good style of coaching.
"I love it here and English football is perfect for me. I'm very happy to be back."
