He's a mainly defensive player and I've always thought similar to Michael Bradley if that helps (probably doesn't). Looks great as the main man but disappears on the big stage every time.
I think Delaney would be great in the current Propper role. The Dutchman could back up all 3 central spots and get plenty of games then Kayal is a natural 5th choice and extremely capable in any of the 3 spots very much becoming 'the Sidwell' of next season.
Doesn't add a lot of pace but would...
He seems to be a deep lying midfielder who is no worse than what we have at all the key attributes for that position, but who chips in with more goals and assists whilst being a good age and value for money. Could very well be the number one target this summer if at a price we feel acceptable...
