Definitely like this signing. Not only is it a bargain but we've finally got a winger who, despite playing on his 'wrong' side, is happy to hold his width and provide dangerous passes and crosses from wider areas.
He doesn't have to be a world beater, but if he helps create both chances and space for Salah (and potentially Fekir) then it's job done. The fact that he's got serious pace and skills is a bonus. Just get tracking back lad!
