While the Champions League clash between Atletico Madrid and Chelsea was eagerly anticipated, football fans were looking forward to something else before the fixture.
Diego Costa completed his move from Chelsea to Atleti on Tuesday and it was always going to be interesting to see what happened when he bumped into Antonio Conte.
In the summer, Conte decided that there was no space for the Spanish striker that helped him win the league by sending him a rather harsh text message.
"My relationship with the coach has been bad this season. I suppose I’ve had a bad season so I can’t go on," Costa said rater this summer.
“I’m going to be honest, the other day, [Antonio] Conte sent me a message saying he does not count on me for next season, so I’ll have to find a way out."
And he did in the form of his former club.
However, a meeting between the pair never did happen before the game and the first time we saw Costa was when he was taking his seat ahead of kick-off.
While he can’t play until January, Costa will be making himself comfortable in the stands at the Wanda Metropolitano in the meantime.
It must have been a difficult match for the striker to watch but he certainly didn’t hide his emotions.
When Michy Batshuayi scored with the last kick of the match to give Conte’s side a sensational 2-1 victory, the camera panned straight to Costa in the stands.
