TONY MOWBRAY today revealed Scott Brown will not play any part in tomorrow night's Champions League qualifier against Dinamo Moscow.

The midfielder - out of action since undergoing an ankle operation at the end of last season - has been training with the first team for the past two days.

Barry Robson has also made a welcome return after recovering from his groin surgery.

But Mowbray believes it is too soon for either man to come into contention for the first leg tie.

The manager said: "Scott is not going to be involved tomorrow. He has trained the last couple of days, which is very positive for us.

"Barry Robson has trained as well the last couple of days, and it is great news that they are getting closer.

"But, when you have been out for as many weeks as these lads have, it is not a question of training two days and coming straight back in."

Mowbray is confident he already has enough fully-fit players available not to have to take any risks in what will be his first competitive game in charge of Celtic.

He has been boosted by the way they have trained since returning from lifting the Wembley Cup at the weekend and reiterated that the performance of the fringe players who beat Spurs on Sunday has given him "food for thought."

While the focus is on tomorrow's match, Mowbray is also continuing to look for more players to bring into the club.

And Stockport defender Josh Thompson could be the fifth new arrival of the summer.

The 18-year-old was on trial at West Brom when Mowbray was manager there, and he confirmed that negotiations are taking place to see if a deal can be struck to move him to Parkhead.

However, Mowbray emphasised Thompson is being viewed not as someone who could step straight into contention for the first team, but a youngster who could be developed within the club's youth structure.

"I would suggest he is not coming for a trial because I know all about him," said Mowbray. "Are we buying him? There's someone else you should be maybe asking that question because I don't know where negotiations are.

"He is a very young player and nowhere near our first team. He's a talented young boy who is at a club who are in a bit of financial difficulty.

"If it's something they would like to do, and it can be done, then I think I would have no problem with that. If it can't, then we wish the boy good luck in his career."
