Sherwood revealed his attempts to recall Carroll from his QPR loan to help boost his midfield options, which he says is missing the right type of player to make it a top Premier League winning side.
"We miss that player - I'm not saying (Mousa) Dembele can't do it because he can pick it up and he can dribble - but we miss someone who moves that ball and passes it between the lines very quickly, and he assists the assister.
"Gareth Bale needed that ball very quickly and I think Luka Modric got it to him very quickly. I think Tom Carroll was that player - he can do that, absolutely. I tried to bring Tom back (in January), it just wasn't possible."
