Chelsea assistant coach Willy Caballero defended the decision to take off Cole Palmer during the 2-2 draw with Bournemouth after supporters at Stamford Bridge reacted furiously to Enzo Maresca’s substitution.Taunts of “you don’t know what you’re doing” rained down on the home dugout when Palmer – who had been one of his team’s best players – was brought off in the 63rd minute as the hosts chased a winning goal to put an end to their poor Premier League form.It is now one league win in seven for Chelsea, though afterwards Caballero insisted that head coach Enzo Maresca, who was absent from his post-match media duties with illness, remains an “example” to everyone at the club.
