Palmer received his first booking following a clash with Mateus Fernandes, then saw red in the 80th minute for a late challenge on former Chelsea midfielder Conor Gallagher. His dismissal came shortly after Mike Penders’ own goal had given Tottenham the lead, leaving Chelsea with little time to recover and a numerical disadvantage to overcome.
Mathys Tel scored Tottenham’s second in the 87th minute, completing a difficult evening for Alonso’s side at Stamford Bridge.
Asked about the match and Palmer’s red card, Alonso said the first goal had changed the contest before the dismissal made Chelsea’s task even harder.
“Well, about the game, for sure we are disappointed with the result, with the performance. Half time we have spoken, I had the feeling that it was going to be about the first goal, the second half it was being tight, some half chances from them, some half chances from us, it was going to be about the key moment and once we have conceded the first goal it has changed everything.
"Straight away almost when we wanted to have a reaction, the red card and it went the other way and probably we can do better, so it is one to reflect in this big game that it was and it is a good opponent, the performance is one to improve.
Alonso had not yet reviewed the incidents on television but accepted that Palmer may have been fortunate to remain on the pitch after his first booking. He said the episode needed to become a learning experience for the player and the wider squad.
“Yeah, absolutely, I haven't seen them on TV but as far as I have been told that probably he got it right, so for sure for Cole but for everyone. We think [up until] now we haven't received any red card and we need to continue that way because we need to have this maturity to deal with difficult moments, when you have conceded 1-0, still probably was 15-20 minutes to go, so we have to be on the way. I need to check the action to talk with Cole but it is one to learn for the future for sure.”
The Chelsea manager was also asked whether Palmer’s recent disciplinary incidents raised broader concerns about his temperament. Alonso rejected that suggestion as a wider character issue, but said the moment required composure.
“Today, for sure, yes, but it is not a concern, I think that Cole when he is focused on the game, when he is enjoying and today after the 1-0, it is a moment to keep calm, a moment to keep mature and for everyone.”
Palmer’s dismissal compounded Chelsea’s frustration after a tight match had turned against them. The forward will now serve a suspension, while Alonso’s immediate focus is on improving his team’s response to setbacks.
The manager’s message was not limited to one player: Chelsea must show greater maturity when a match becomes difficult, particularly when there is still time to recover a result.
