Roy Keane is enjoying the dressing room banter at Celtic but insists he will never become too close with any of his new team-mates.

The former Republic of Ireland captain has earned a chilling reputation having controversially stormed out of the World Cup in 2002 and has been involved in other infamous incidents in the past.

But the 34-year-old admits he is settling into his new environment well, although there is no chance of forming any special bonds.

"No I never do that," said Keane. "You can’t get too close to them. There are a few senior lads who I played against a few years ago and of course I know Dion (Dublin) from our United days.

"I am actually enjoying the banter with all of them so we get on fine. Most footballers tend to gel with each other immediately. I enjoy the dressing room banter and it’s different craic. There are some decent lads there."

Keane has also proved some people wrong by forming a quick understanding with Neil Lennon in the centre of midfield. But the former Nottingham Forest man believes the reason it has worked comes down to his team-mates.

"It has worked over the last few weeks but that’s credit to the rest of the team," Keane told Celtic TV. "Stilian (Petrov) has showed his versatility by playing over on the right and last week up the front. If I can play with Neil all well and good, and he is an excellent player and he has helped me as well."

Keane has also impressed but he has promised the Hoops faithful they will see "plenty of improvement" from him in the next few weeks. Celtic are seemingly on course for the Bank of Scotland Premier League title and have a CIS Insurance Cup final ahead.

Keane continued: "My form has been okay but I said it would probably take me seven or eight games to get into the swing of things. I still think there are certain areas I need to improve on. There is plenty of improvement to come and hopefully that will come in the next few games.

"I have played a few games now and I have felt a bit fitter and sharper so I am settling in."
