Chelsea captain Cesar Azpilicueta has named the Chelsea player that will be key for the club this season.
Azpilicueta is convinced Lukaku will be an important player for the Blues this season after learning from his bad experiences and gaining maturity.
Azpilicueta said: “With the years you gain maturity. You learn from bad experiences. When you experience different things you gain this maturity.
“Romelu has always been a great personality, willing to improve his own game, trying to help the team. I have no doubt he’s going to be a key player for us.
“We are so happy to have him this season. You can see his strengths, his personality, his goalscoring, his assists, the way he plays. Even though Arsenal was his first game and he only had one week of training.
“But he knows the club. He has been here before. He has the ambition and the desire to be successful and help the team keep winning trophies.
“When he was at Chelsea the first time you have to take into consideration it was a different group. He was very young. It wasn’t easy for him. But he worked his way to be at the top. A few other loans to other teams and then he was sold. Another country, to Italy, to prove his worth.
“Now he’s back already to the Premier League and he showed his quality. In life, you grow. You gain experience. You learn where to go and where not to go on the pitch, to be more dangerous.
“Romelu has always shown his personality. With age you become more confident and now he’s in a different stage of his career.”
