Frank Lampard believes the arrival of Edouard Mendy at Chelsea can help push Kepa Arrizabalaga, though the Blues manager did not rule out the possibility of the Spain international leaving.
Kepa was entrusted to start the Premier League season, but Chelsea have been in pursuit of another goalkeeper throughout the window.
Mendy arrived this week in a £22million transfer from Ligue 1 club Rennes, with Kepa having made a calamitous error in Chelsea's 2-0 defeat to Liverpool last weekend.
While Mendy will not start against West Brom on Saturday, Lampard did not confirm whether Kepa would play, and also did not close the door on the world's most expensive goalkeeper potentially leaving on loan.
'There's no clarity on that one yet, about what will happen, and I'm not going to speak about the maybes of what might happen in the future," Lampard told a news conference when asked if Kepa could be loaned out.
"I think the most important thing right now is the game this weekend, in which Mendy won't be involved in. I'll have conversations with all the goalkeepers and be very open about it and we'll see the way to move forward.
"I'm not going to talk about who starts because I need to speak to the goalkeepers themselves and I'd much rather it be a conversation I had with them rather than they read it from yourselves.
"I think with the dynamic of the goalkeepers, we know we've had problems in the goalkeeping area in the first two games of the season and at times last year. We know that and I think we can be very honest and open about that, and Kepa is in that search for the best performance levels.
"Mendy comes in of course to be big competition in that area. Now it's about how we move forward, about trying to get that performance level as best as can be."
Mendy has followed in the footsteps of Chelsea great Petr Cech, who joined the club from Rennes in 2004 and now serves as the Blues' technical and performance advisor.
Recently, Cech has also been out on the training pitch with the goalkeeping unit.
"I think a combination of both," Lampard said when asked if Cech was coaching or simply keeping himself fit.
"With Petr, he has so much to give on that side of things. Obviously his day job here is to be technical advisor and he's a great help to me on that front.
"I think having Petr train with the goalkeepers and bring his experience is a great thing because he still has great quality. I think he retired pretty young to be fair. So he's training and keeping fit, which I think is healthy for him and the goalkeepers in the squad and that's as far as it goes. I've got absolutely no problem with it.
"It's something that I think is positive for the goalkeepers as a whole and Petr enjoys doing it, so why not give back and give that experience to the goalkeepers."
