Chelsea boss Mauricio Pochettino admits they're wary buying a new striker.
Chelsea have lost Christopher Nkunku to January due to a knee injury, but with Armando Broja returning to full fitness Pochettino is wary blocking his first team path.
Pochettino said, "We are working of course. We're seeing all the options we can manage on the market. I think all the clubs are the same as us.
"In the same time we are keeping eyes on Armando Broja because I think we cannot forget him. We cannot stop him by bringing a profile of player that could stop his evolution.
"We really believe in him, he can be a really important strike for Chelsea. We need to be careful."
