Eden Hazard's disappointing start to life at Real Madrid is possibly a result of him gaining weight, according to former Arsenal manager Arsene Wenger.
Los Blancos paid Chelsea €100m plus add-ons to bring the Belgian to the Bernabeu over the off-season. However, he has failed to live up to that price-tag thus far, scoring just the solitary goal in his ten appearances for Zinedine Zidane's side, though the 28-year-old had to wait until September for his debut after picking up a thigh injury in the summer.
Wenger believes those fitness struggles have had a significant baring on Hazard's form in the Spanish capital, claiming he is heavier now than when he was still playing for the Blues.
Speaking to beIN Sports, the Frenchman said: "We have not seen the Hazard we know in England. He is not the type of guy to be [intimidated at Madrid].
"I think it was more down to physical reasons. He became too heavy. If you want to make a horse lose a race, you put 2kg on a horse of 500kg and it's enough [to slow them down]."
Hazard has admitted he has found it difficult to replace Cristiano Ronaldo at Real Madrid, having taken on the number seven jersey, which used to belong to the Portuguese superstar.
Despite the problems surrounding their marquee signing, Madrid are currently joint-top of La Liga, with leaders Barcelona only ahead of them on goal difference.
They are also on course to qualify for the knockout stages of the Champions League, recovering from a 3-0 opening-night defeat at the hands of Paris Saint-Germain to take a firm grip on second spot in Group A.
Real's 6-0 destruction of Galatasaray on Wednesday evening all but sealed their progress. Teenager Rodrygo grabbed a hat-trick in that victory, though Hazard was once again a peripheral figure.
