Thomas Tuchel identified Eden Hazard as just one of several Real Madrid threats towards his Chelsea team, speaking in his press conference.
Hazard will be hoping to face the side he left two years ago when the Blues take on Madrid in the Champions League semi-final tomorrow.
After several seasons of tearing it up in England, the 30-year-old has been torn apart since moving to Spain.
Repeated injuries have swallowed Hazard’s game time hole, limiting him to just 37 appearances for Los Blancos.
He recently recovered from his latest problem, featuring in the final 15 minutes of Madrid’s 0-0 draw with Real Betis last weekend.
The Belgian international should play some part against Chelsea, most likely coming on as a substitute.
Tuchel was asked whether he had discussed with his squad the impact that Hazard could make if deployed by Zinedine Zidane.
“Eden is a top-quality player,” said the Blues boss.
“He was the key player here for many years at this club and in this league, which is one of the hardest in the world and a tough one to decide matches.
“Eden did it constantly for this club, so I have the biggest respect for him.
“Of course, we talk a lot (about him), because he’s a big player for this club. Many people here (Chelsea) know him very well.
“He was a key player for this club and now he plays for Real Madrid. He’s ft and he had a comeback in the last game for some minutes to be ready tomorrow.
“I’m sure he will want to make a point and prove himself. They (Real Madrid) have so many quality players, we have to face the challenge with confidence.”
During his seven-year stint at Stamford Bridge, Hazard had a massive hand in two Premier League triumphs, two Europa Leagues, an FA Cup and a League Cup.
In 352 games, he scored 110 goals and was voted Chelsea’s Player of the Season four times.
Some of the shine to his glittering legacy left in London has faded following his transfer to Madrid.
But Hazard could certainly reapply some gloss if he helps the La Liga champions past the Blues and into another European final.
