NOEL KING is prepared to field Robbie Keane as a lone striker in Friday's World Cup qualifier with Germany.
Trapattoni selected him there in the Euro 2012 defeat to Spain where he was an isolated figure for much of the game.
Questions have been asked about whether the LA Galaxy star is suited to that brief, but King – who spoke with Keane on the phone after he was brought in on a temporary basis – feels he is capable of taking on the difficult assignment.
"He can certainly do it," the manager said yesterday.
"Anthony Stokes can do it as well and there are other players in the group who could possibly do it.
"We're trying to get the balance right against the Germans and that's what we are working on."
The deployment of Marc Wilson is another major issue facing the stand-in boss.
Wilson established himself as Trapattoni's first-choice left-back in the final year of the Italian's tenure but is now operating as a central midfielder for his club.
He was used in both roles in training yesterday and could also come into the mix for a centre-half berth next to Ciaran Clark. Joey O'Brien, who sat out yesterday's proceedings along with Anthony Pilkington and Kevin Doyle, would be vying with Stephen Kelly for a start if Wilson moved into the engine room.
"These are the issues," said King, "I've seen him (Wilson) play midfield for his club.
"That's great that there is versatility in the group, like Joey, who didn't train today."
King will leave it late to confirm his team and will examine other options in training this morning before flying to Cologne early in the afternoon.
