Manchester City goalkeeper Joe Hart admits he has had no talks with the club over a new contract.
The England international is tied to the club until the end of next season but, while he has been first choice so far this term, he still faces competition from summer signing Willy Caballero.
Hart has also seen team-mates David Silva, Sergio Aguera and Kompany sign new deals but has had no hint he is next in line.
"If a new contract is on offer then it's news to me," he said. "I've got almost two years left on my current deal and that's all I know about my contract situation."
Manchester City signed £32m defender Eliaquim Mangala from Porto this summer but have yet to play the France international, with boss Manuel Pellegrini preferring veteran Martin Demichelis alongside captain Vincent Kompany.
"We thought we needed a good defender but not necessarily in the month of August or September," Pellegrini said. "We needed a young defender and we thought Mangala was the correct player.
"We will see when he starts playing. He will play but he does not have to play immediately. It is four months without him playing a game but why must we start him immediately when we have two good defenders?"
