Manchester City boss Pep Guardiola admits he hates dropping players.
Last summer, Guardiola saw Gabriel Jesus and Oleks Zinchenko join Arsenal, while Raheem Sterling left for Chelsea.
"The most difficult by far, miles, miles away," Guardiola admitted when asked about dropping players.
"If you are a little bit sensitive, by far. There's no solution, it's hard.
"When players deserve to play and they cannot play, it kills me."
