LONDON -- Antonio Conte is "confident" Diego Costa will stay at Chelsea but insists his new contract can wait until the summer.
The Spain striker's future has been the subject of speculation since January with a move to the Chinese Premier League rumoured.
The 28-year-old is reported to be in advanced negotiations over a new five-year deal to commit his future to Stamford Bridge, but Conte says it can wait until the season is over.
"I don't know about this situation," Conte said when pushed on whether a new Costa deal was imminent. "I think it is very important to focus on the present and not to look so far forward.
"I think now for the players, for all the people who work for Chelsea, me, to be focused on the present, then at the end of the season we will see the situation."
Costa has struck 15 Premier League goals to help Chelsea to the top of the table and Conte is confident the player will stay.
"Yes, I'm confident [he will stay]," Conte said ahead of the FA Cup fifth round game against Wolves. "It's important for the group concentration for tomorrow's game versus Wolverhampton.
"We must go to the next round and then I repeat, this situation will be better to face at the end of the season."
Conte will have John Terry available for the game against Wolves with the Chelsea captain overcoming an ankle knock.
The former Juventus boss also insists David Luiz's knee injury has responded well, but that the Brazil international and Marcos Alonso could be rested.
"John Terry is fit. He's OK. All the players are available," Conte said. "There is a situation that is better to keep under control for Marcos Alonso -- a bit of rest.
"Also for David Luiz and a big opportunity to give him a week to recover very well and prepare for the next game. All the players are in a good form."
