2) Aaron Lennon (Everton)
Aaron Lennon was a regular starter for Everton till the 2015-2016 season, but after being detained under Mental Health Act last season, he has been far away from a starting place. The 30-year-old winger was detained under the Mental Health Act in May after police found him at the side of a road in Salford.
Lennon said in the summer that he wants to play regular football again. He recovered from his medical condition before the start of pre-season. But Koeman didn't play him much which even prompted him to try to force a loan move to Burnley, which eventually got rejected.
But just recently, the former Tottenham man showed signs of good form against Chelsea in the EFL Cup. He brought pace, intensity and aggressiveness to Everton's attack which eventually made Chelsea work hard for their win.
