Adam King
We've already seen Adam King play for Swansea and boy is he good. Having played against Arsenal in the Premier League last season, King was instrumental in ensuring his midfield didn't lose their composure to Arsenal's ever-changing attacking combinations.
An excellent reader of the game and one who can pass from anywhere on the pitch, King is one for the future and definitely the kind of the midfielder Swansea need – especially since they lost Jonjo Shelvey to Newcastle in January.
He too was sent on loan to Crewe last year for a few months where he impressed the Swansea hierarchy who later offered the youngster a new three-year deal to stay at the club. The Scotland Under-21 international could make his debut for the Swans this season and should be another midfielder we've to watch out for.
