Chelsea boss Thomas Tuchel admits he can understand the upset amongst Inter Milan fans losing Romelu Lukaku.
The Belgian left Inter to return to Chelsea in August.
Tuchel said, “I'm sorry for the Inter fans, but like everyone, we try to improve our formation.
“We were looking for a very physical striker, a point of reference, a player with a personality who could lift the pressure off the shoulders of the younger players and give us the chance to play faster football.
“Returning to England, where he played as a young man, was important for him. I knew he was an extraordinary person."
