NEWCASTLE manager Bobby Robson has pledged to do all he can to help England coach Sven-Goran Eriksson, including releasing Kieron Dyer for this month's friendly against Spain.

The former England boss has warned Eriksson that Dyer is struggling for fitness after his recent injury problems.

But the midfielder remains one of the brightest hopes for the Swede, with Robson describing his performances out of position as a striker this season as ''breathtaking.''

The Newcastle boss will have left Eriksson in little doubt of the midfielder's qualities when he met up with the Swede at Stamford Bridge on Wednesday night.

Whether Dyer is actually fit to play for England against Spain at Villa Park in just under four weeks remains to be seen as he has not trained for the past two weeks due to a shin problem and is still in some pain.

But Robson insisted: ''If Sven sees him as one of the squad players then I'd allow him to be picked, to go and train, and to play if Sven felt that he should play him.

''When he knows about his condition, he might think that he won't play him but I'd allow him to go.

''He can have every English player he wants. You can't run an England team unless the managers cooperate. So I'd give him the chance and it's up to him to take it.''

Robson, who said he would know more next week about Dyer's likely ability to start the game if required, would not have played him at Chelsea if Alan Shearer, Carl Cort and Kevin Gallacher had not been out injured.

Needs must, however, even though the 22-year-old is considered ''too valuable'' to risk, and he displayed the promise already identified by Eriksson as he gave Frank Leboeuf a series of headaches with his pace.

Having seen Dyer impress as a central midfielder against Italy last November, as well as watching him as a wing-back on videos of past England games and as a striker at Chelsea, Eriksson will also have noted his versatility.

He has the exuberance and turn of pace which England need and the Swede will surely be keen to harness that talent.

It was Dyer who foxed Leboeuf with a shimmy to reach the byline before sending over the deep cross from which Christian Bassedas put Newcastle ahead at Stamford Bridge.

While Dyer's influence later faded due to his lack of match fitness, Robson was simply relieved he had not, as previously feared, suffered a stress fracture of his shin.

''He has to go and train and play and see what happens. He has got a problem with a cyst and he's on a couple of aspirins a day to kill the pain,'' he revealed.

''That's the best form of treatment. He's all right, he just wasn't fit after not training for two weeks.

''I took him off when we were 3-1 down. I gave the game up and played for Sunday. He'll be a different player then against Southampton.''

Eriksson could even make it to St James' Park for that game to see Dyer in action again, although Robson had warned him not to expect miracles from the midfielder at Stamford Bridge.

''Kieron has been quite breathtaking for us up front. He has played as well for us as any striker has done in the Premiership,'' he said.

''He's scored some marvellous goals and he set up a clever goal against Chelsea. It was his poorest match but he hasn't been training.
