Newcastle United boss Alan Pardew admits he wants to add a greater physical presence to his squad this summer.

Pardew feels his team lack strength in the air.

"The big fall-down has been the centre-backs scoring goals from set-plays. We need to have more dominance in that area," he said.

"It's all well and good saying that the set-play problem is down to tactics, delivery, whatever. Ultimately you need (players of) six-foot four (inches) to go and head it in, or at least make first contact.

"We haven't had that all year and it means all our wins have been one-goal wins, apart from Wigan and Southampton.

"We're not the strongest attacking-wise (from set pieces) and that is an area that we need to look at."
