Eden Hazard paid tribute to Cesc Fabregas after the Spain playmaker appeared to bid farewell to Chelsea.
Fabregas was tearful as he applauded all sides of Stamford Bridge following Saturday's 2-0 FA Cup third-round win over Nottingham Forest, during which he had a first-half penalty saved.
The 31-year-old's contract expires this summer and he has been linked with a January move to Monaco, and a reunion with former Arsenal team-mate Thierry Henry.
Fabregas joined Chelsea from Barcelona in June 2014 - two years after Hazard arrived from Lille - and has won two Premier League titles, plus the 2015 League Cup and 2018 FA Cup, during his spell at Stamford Bridge.
"In five years, I can say that I was lucky to play with him," Hazard said.
"Since the beginning when he came, we saw it the first year, we won the double together.
"Top guy on the pitch, off the pitch, a great friend of mine.
"Just admiration about this guy. I hope he will have a good future. It's a bit hard now, but he's still very good and he will enjoy."
