Eden Hazard has admitted he sent a message of apology to Jose Mourinho after the coach's sacking by Chelsea in December.
Hazard was named the PFA Player of the Year as Chelsea stormed to the Premier League title last season but his form in 2015-16 has fallen well short of those standards.
The Belgian did not score his first goal of the campaign - a penalty against Championship side MK Dons - until the end of January and says he felt guilty about Mourinho's dismissal.
"I sent him the message to say I was sorry he had gone and, well, just that I was sorry," Hazard told the Guardian. "We'd enjoyed all that success together last season, but this time round we hadn't.
"I felt a little bit guilty because I'd been player of the year. I'd been one of the most decisive players, and this year I'd performed less well.
"I hadn't been at the same level. So I sent that text to Jose and he came back to me, wishing me all the best for the future. For a team of champions to go through what we have this year even I can't explain.
