Champions League: Did Arsenal over-celebrate semi-final win over Atletico Madrid?

Tuesday’s celebrations included Arteta and his players joining hands and running towards each end of the Emirates.

Bradley Busch is a chartered sports psychologist who runs Inner Drive, a sports psychology training centre, and he told BBC Sport the collective celebration indicated a “very healthy team and squad mindset”.

“The technical phrase that is used in research for this is known as ’emotional contagion’, which basically says behaviours and attitudes and unity can spread and ripple through the team,” he said. “One way you can do that is through celebrating together.

“On a more fundamental level, players aren’t doing that to try to improve future performance – they’re doing it because it’s a sheer release of thinking and breathing about this stuff 24/7 and realising your goals.

“In what is such a high-pressurised environment I think it’s really healthy for it not all to build up and bubble, and to celebrate on the pitch.”

Busch added that anyone suggesting Arsenal‘s reaction was over the top “feels a bit like the old celebration police going on there”.

“The nearest you can get to defining over-celebration is anything that negatively impacts the future performance,” he explained.

“We sometimes see that with players and teams during the match – where they might think they have already won, which can lead to showboating or playing with much less intensity, or if it’s interrupting the preparation for the next match. But this is a world away from that.

“As a Tottenham fan, I absolutely do hope it’s a case of over-celebration – but that’s more of my personal opinion than professional one!”
