The Portuguese playmaker played a key role in helping Fulham to promotion back to the Premier League but Liverpool have now snapped him up for an initial £5m.
Yan Couto (Manchester City)
The right-back has yet to play for his parent club, but he did have an impressive season out on loan at Portuguese side Braga, who made it to the Europa League quarter-finals.
