Former Blues winger Cole pointed out that Pulisic or Ziyech ‘weren’t at their very best’ against the league leaders.
‘The difference between the Arsenal performance and Chelsea performance was the performances of Martinelli and Saka in the Arsenal game,’ Cole told BT Sport.
‘On them transitions, being able to get the ball, drive and do something.
‘Today, Pulisic and Ziyech weren’t at their very best and I think when you talk about the structure of the team, that’s where Chelsea were lacking a bit today.
‘When they got the ball in midfield, Kovacic made some excellent challenges and won the ball, then it went to Pulisic and Ziyech and they didn’t find the right pass.
‘You have days like that sometimes as a No.10, I’ve had plenty of them myself.’
