A training game put on by Thomas Tuchel saw chaotic scenes ensue at Chelsea's training camp in Ireland, which saw half the Blues squad accuse the other of cheating after losing the game.
Tuchel split his pre-season Chelsea squad into two and tasked his side with a heading game which saw each player in turn throw a ball to a team-mate to score with a header, before rushing in goal to stop the other team's identical effort. The winning team was the first team to score five goals.
The losing group - which included the likes of first-team stars Tammy Abraham and Davide Zappacosta - accused the other team of making up their total and asked Tuchel to check the amount of goals they scored using the cameramen filming the game.
