Celtic manager Neil Lennon was unimpressed with reports which claimed Uefa were "irritated" by his threat to send a DVD of complaint about Spanish referee Alberto Mallenco.

Lennon was raging at the official for not punishing severely enough the Juventus players who manhandled his men during the first leg of the Champions League last-16 clash at Parkhead last Tuesday, which the Italians won 3-0.

"I think it is a load of rubbish myself, there is no direct quotes from Uefa so I would disregard that story," said Lennon.

"We may not (send a DVD). We have compiled something but we might just do it through a phone call.

"All I want is clarification. If that is allowed in the game then fine, we will start doing it, or were Uefa happy with the referee's performance and some aspects of the game? That's all."

Lennon revealed skipper Scott Brown will see a specialist to ascertain whether or not he is to go under the knife.

The midfielder sat out the United game at the weekend with an abductor problem and will miss the trip to Perth.

Brown, however, has been bothered by an ongoing hip problem this season which was thought at one time to require surgery, but both problems are to be addressed.

Manager Lennon said: "Scott will be seeing a specialist regarding his abductor and we will wait on the outcome of that.

"We will have a look at what he had before and he might require surgery, we are not sure yet, we will see what the specialist says but hopefully that won't be the case."

Celtic are 18 points clear of Motherwell at the top of the table but Lennon insists complacency won't be a problem.

He said: "We want to keep the run going.

"There has been no signs of complacency, we have our targets to reach and some players might have targets so we are pretty focused."
