Chelsea manager, Thomas Tuchel, has admitted he was wrong to bring Romelu Lukaku on during their 3-2 defeat to West Ham on Saturday afternoon.
Tuchel introduced the Belgian striker in the second half after Kai Havertz picked up an injury.
Lukaku made just three appearances following his return from the ankle injury he suffered in October.
Tuchel has now said the 28-year-old was not “physically” ready to play 45 minutes of football after the game.
Speaking to Chelsea’s official website, Tuchel said: “It’s my fault. I don’t think he is ready for 45 minutes of physicality but still, we decided to bring him on for his height because we lost Kai.
“Kai had a crucial role in defending set-pieces, which is a huge threat from West Ham, so this is on me. I took the decision so it’s my responsibility.”
