Chelsea boss Mauricio Pochettino admits he's seeking a 'James Ward-Prowse-type' this summer.
Pochettino concedes he wants to see a set-piece specialist to the West Ham midfielder signed.
He said, "We work a lot on set-pieces.
"After that, it is about the quality of the player. It is about the takers. We don't have a specialist. If you want to be good in set-pieces, we work a lot. But then you need good takers.
"It is not down to the work. We work similar. But the problem is to have good takers. We were talking about trying to find for next season a good specialist.
"Look at West Ham. What changed? After and before? It's not the same. The taker is Ward-Prowse. You add a player like him, you increase the percentage. That is football. Football belongs to the players. Not to the specialist (coaches)."
