1. Marko Marin
The forgotten German winger will have to be the one who’ll be sold. Bought for £6.5m 2012, Marin never settled in Chelsea and was loaned off to Sevilla. Marin is known for his great passing and creativity but he’s also known for his constant injury problems. Constant niggles have not allowed him to settle down in Chelsea but he has somehow managed to settle in Sevilla despite having hamstring issues and has expressed his desire to continue playing for Sevilla on a permanent deal if the clubs want him to.
