Ibrox boss Warburton hoping to bring in new face before Monday's clash with Morton

Rangers last week had two bids for St Johnstone winger Michael O’Halloran rejected while they continue to be linked with Brentford midfielder Toumani Diagouraga.

Warburton maintained his stance of not talking about specific players but he is optimistic over success ahead of the Cappielow game.

“I’m very hopeful we will do (bring in a player),” he said. “We’re making good progress. If we find the quality that we think improves us then we will make that move, but sometimes to secure that quality takes time.

“The important thing is not to take players for players’ sake. Our squad is more than good enough right now to achieve what we want to achieve.

“It’s really important as a club that we do our homework and determine what we think is the right valuation. We could be wrong but we will determine what we think is the right valuation and stick to that.

“If there’s some small flexibility then that’s up to the owner and the board. But it’s really important to know your market and recognise what represents value. If you can find the value then great but if not then don’t be panicked into buying someone that’s too expensive.”

Rangers have signed wide midfielder Harry Forrester from Doncaster and Polish goalkeeper Maciej Gostomski since the transfer window opened but wingers Tom Walsh and Nathan Oduwa have departed, the former going on loan to Dumbarton.

Warburton said: “The size of squad is lean but we’re lean for a reason. I want everyone to see a pathway into the first team.

“Harry Forrester has come in, Maciej in goal, so we have good cover, but there is no doubt we are lean so if we can add to it we will do.

“We had 19-20 players last week, Nathan goes back and Tom Walsh goes out on loan, so we are tight but I prefer it that way. I want everyone to experience first-team action.

“We have an academy here that’s doing really well, so we can dip into the academy. We have done it before.

“The worst thing for me is to have too many players as opposed to too few.”
