Crystal Palace set to swoop for Wolves duo Dominic Iorfa and Kortney Hause

Wolves face a fight to keep their star England duo of Dominic Iorfa and Kortney Hause at Molineux this summer – with Crystal Palace believed to be eyeing up a double swoop.

The list of clubs interested in the pair is lengthening, with several more thought to have joined the queue after they both excelled during England Under-21's recent Toulon tournament triumph in France.

Palace were already known to be keeping tabs on Iorfa, but it is now believed they have added Hause to their shortlist as well with boss Alan Pardew looking to bulk up his squad for next season.

Palace see Hause as the ideal long-term replacement for Irishman Damien Delaney, who was first-choice centre back (alongside Scott Dann) last season but at age 34 he is likely to move on before long.

Iorfa and Hause are close friends and a double transfer to Selhurst Park may appeal to the youngsters, who both relocated north to move to Wolves (Iorfa is from Southend and Hause from London).

Former team mate Bakary Sako is of course at Palace, as is Wayne Hennessey.

But if the Eagles make a bid for either player they won't be short of competition.

Arsenal, West Ham and Southampton are thought to have scouted Iorfa.

The Gunners have also looked at Hause, as have Everton.

And a number of German clubs were said to have taken a shine to Hause during last month's Toulon tournament, in which the two Wolves men both featured prominently – and played in the final as England beat France 2-1 to lift the trophy for the first time since 1994.

Wolves won't welcome any interest in the pair, who both signed bumper new three-and-a-half year contracts last season to tie them to Molineux until 2019.

Iorfa played more games than anyone in a Wolves shirt last season, featuring 46 times in all competitions and winning the club's young professional of the season award for the second year in a row.

Hause's campaign was hit by a troublesome long-term hamstring injury but he still made 27 appearances.

However he was fined by the club after leaking images of the club's new away kit onto SnapChat.

He was also immediately dropped for two games, but Kenny Jackett insisted it was a coincidence.

The Wolves boss recently said of any interest in Iorfa: "I personally wouldn't want to see him go.

"I think we need players in to improve us, rather than letting players go.

"I'm sure everybody at Wolves feels the same way as I do."
