The 48-year-old says that his star man is yet to decide his next club after the Belgian scored a hat-trick in his last-ever appearance for LOSC
The Belgian has been courted by a host of clubs across Europe, most notably both Manchester clubs, but recently admitted that a move to Chelsea may prove tempting after the Blues won the Champions League.
Hazard bagged a hat-trick in Sunday's 4-1 win over Nancy - his last appearance for Lille - and speaking after the game, Garcia denied that his star man had already decided which club he'd be moving to.
"It was a lovely evening, we had a great send-off party for Eden. He still doesn't know where he's going. In the last few weeks he's changed his mind, I believe," he according to RMC.
"Things will be great for him. He's going to be a great player. The best player in the league is leaving it. Eden is a unique player, a guy who's capable of rising to challenges.
"He will remain one of the best players in LOSC's history."
Hazard was recently named Ligue 1's player of the season for 2011-12.
