Chelsea boss Thomas Tuchel has explained his halftime hook for Callum Hudson-Odoi in their stalemate with Manchester United.
Hudson-Odoi returned to the bench, apparently in discomfort, with strapping and ice on his knee, but Tuchel confirmed he was only a 'little injured'.
The Chelsea boss said: "[He was] a little bit injured.
"The reason [he was replaced] was a tactical reason and a little injury, a combination, because we switched to a back five in defence and covered the wide position from [Marcus] Rashford in between [Cesar] Azpi and Reece James.
"In the second half, that was not an option to use Callum there and that's why it was a tactical choice."
