Nicolas Fedor and Efe Ambrose may only have been Celtic players for a matter of hours, but when they took to the pitch to be greeted by the crowd before kick-off at Celtic Park yesterday, they readily talked a very good game.

Ambrose spoke of the club's rich history, while Fedor expressed his appreciation at wearing the No 7 that previously belonged to club legends Jimmy Johnstone and Henrik Larsson. "I will defend this shirt with honour," he said.

There is time enough for them to show their true worth to the club. Ambrose, a 23-year-old Nigerian centre-back, has signed a three-year deal while Fedor – who is known as Miku – has joined from Getafe on a year-long loan. The 27-year-old striker, who is a Venezuelan international but who has a Hungarian father, was Getafe's top scorer last season and he is undaunted by the challenge of facing Barcelona in the Champions League.

"It's not impossible," he said. "I won with Valencia against Barcelona. It's a difficult match, they have the best player in the world in Lionel Messi, but they can lose. I want to play against Barcelona. It's my job to score goals and I scored two goals against Real Madrid last season, but lost the game. Against Barcelona I didn't score, but the team won the game. The team is the most important thing."

Ambrose name-checked Larsson too, but it is Celtic's current status that has brought them both to Glasgow.

There is the SPL championship to be won, as well as a Champions League group that also contains Benfica and Spartak Moscow to be negotiated Their transfers to Celtic Park were in the pursuit of prestige.

"It won't be easy, but we have a good team to pass into the next round," Miku said."

While Celtic were happy to parade two names in Neil Lennon's in-tray, another player insisted he has no plans to depart the east end of Glasgow. The £10 million bounty placed on Victor Wanyama's head was designed to thwart any circling vultures before the transfer window shut, but the Kenyan international maintains he is content to remain at the Parkhead club.

QPR had a £6 million bid for the 21-year-old rejected this week, but Wanyama is happy to park his Barclays Premiership aspirations in the meantime.

He said: "I came here for one reason and the reason was to play in the Champions League, and I don't think about leaving just now.

"The manager is happy and I am happy here. He has been talking to me, but I was not even thinking of leaving. As I have always said, the only chance I wanted was to play in the Champions League."
