Sheffield Wednesday manager Alan Irvine will only name his team to face Crystal Palace on Sunday when he sees fit.

The Owls face a titanic tussle against the Londoners, at the end of which either Wednesday or the Eagles will be facing League One football next season.

Irvine has a full squad from which to select and he insists that a plethora of factors will determine his starting line-up.

He said: "There are many factors to influence team selection, the list can be as long as your arm. I think the average fan picks a team in about two minutes but managers have all sorts of things to consider and for a game like this, you have to consider who can handle the occasion.

"The team is getting close to being picked but you have to look at the training each day, you have to then make sure that everybody is going to be fit and able to put the kind of performance in on Sunday that we are going to need. So I would expect that my team will be picked by tonight/tomorrow morning."

Even the Wednesday players themselves are still to be told the team that will decide the 2010/11 destiny of the club. Opponents Palace are thought to be in a similar situation as the clock counts down on the biggest game of the Championship season so far.

Irvine added: "I've not decided yet on when to tell the players. The easiest way of all is to tell the players tomorrow morning, do the work on the training ground and send them away. But you have to think about all the factors that could mean that is maybe the wrong decision.

"And, of course, there's the fact that people are having to think about it for a little bit longer for what is already a very high pressurised situation. It's something that I have to bear in mind.

"The other thing is that if we are planning on doing something a little bit different, I don't really want Paul (Hart) to know. And unfortunately, things seem to find a way of getting themselves out these days an awful lot quicker than in the past.

"But everyone is fit, we have a full squad to pick from, and that is a terrific situation."
