Arsenal manager Arsene Wenger had earlier confirmed Celtic's interest in the 24-year-old Swiss defender who himself said: "I am very honoured that a big club like Celtic are interested in me and a loan deal right now would suit me perfectly."

However, the Celtic boss, speaking after Niall McGinn's first-half strike gave the Hoops victory over Morton in their Active Nation Scottish Cup fourth-round tie at Cappielow, said: "There has been no bid.

"There is no decision (to be made) from Senderos.

"You have been watching too much television."

Told that Wenger had confirmed Celtic's interest, Mowbray replied: "We have an interest in many players, I would suggest.

"For whatever reason, that came out today but that is only one enquiry of many (players) that we have asked about.

"So I wouldn't be holding your breath too much at the moment."

Mowbray admits there should be one new face added to his squad tomorrow but refused to reveal his name, although it is thought to be Norwegian teenager Thomas Rogne.

He said: "I don't think tomorrow's signing will be a major acquisition but it will be an important one as we try to build the club.

"Sometimes you build the club with marquee players and other times you bring players in who you wait to blossom."

Mowbray had no real concerns about the outcome of tonight's cup tie against the Irn-Bru First Division side despite the narrow victory margin.

"Cup football is all about getting into the next round and we have managed to do that," the former West Brom boss said.

"My heart wasn't in my mouth, I think we were reasonably comfortable.

"I genuinely don't think they threatened our goal too much in the 90 minutes.

"The second goal would have had us sitting comfortably but ultimately we didn't need that.

"It wasn't as fluent as it has been over the past few months and I don't think it was ever going to be the case.

"It was going to be a difficult night but we managed to get into the next round."

Morton boss James Grady claims his side were undone when they switched off for a moment in the first half but insists he will be happy if his players produce similar performances in the First Division.

Grady said: "We started well and we were up for it from the start.

"We contained Celtic for long spells but I have to look at the goal.

"It was a cheap goal to give away in terms of it came from a throw-in when Fortune was getting marked on the wrong side.

"It is a basic error.

"He gets along the by-line and we were exposed.

"But I'm proud of the players, they gave us everything they had and I said to them that if they give us that performance then most weeks we will win games in the First Division.

"They have to treat teams like Dunfermline, Inverness and Airdrie the way we treated Celtic and then we will get ourselves in to a more realistic position."
