Chelsea boss Frank Lampard has praised the attitude of Kepa Arrizabalaga after dropping him last week.
Willy Caballero was chosen ahead of Kepa for Chelsea's last game - a 2-2 draw at Leicester City.
"The reaction from Kepa has been good as I'd expect, training hard, head down," Lampard said.
"I haven't had lots of conversations with him this week and it'll be a decision for me to make. I've decided but you'll have to wait to find out.
"It doesn't matter how you came to the club, what age you are, what part of your career you're at. If it did, then I'd have to pick the whole team on how much they cost and it can't be that way. All the players know that.
"It's all about how you train every day and how you play on match day. I have to have that competition within the squad."
