Kevin De Bruyne was spotted hitting a wall in frustration after being substituted through injury in Manchester City's FA Cup semi-final defeat to Chelsea.
The Belgian suffered an ankle injury and will be assessed today, but was able to hobble off and into the dressing room without help. Pep Guardiola said after the game: "I don't know - he has pain. Tomorrow we're going to make a test with the doctors but it doesn't look good. We will see tomorrow."
Footage from the FA Cup's 'Tunnel Cam' from Wembley shows De Bruyne focussed throughout the afternoon, before being visibly frustrated at his new setback as he limped to the dressing room on his own.
We've looked through the video and picked out the talking points from the behind-the-scenes access, from De Bruyne's reaction to a number of players from both sides renewing acquaintances.
De Bruyne's anger at injury setback
Kevin De Bruyne walked straight down the tunnel after being substituted with his ankle injury, and while he was walking unaided he was clearly limping as he headed to the City dressing room.
As he entered the tunnel area, the Belgian hit a wall in frustration, showing his annoyance at being forced off. He was closely followed by a member of staff as they entered the dressing room before closing the door behind them.
A new leader in the squad?
As the players arrived, checked out their surroundings, and headed out for warm-ups, there was a confident mood among the City squad. While the City players gathered before warming up, it was Raheem Sterling bouncing a ball in the tunnel and being vocal to his teammates.
It was Sterling again who was vocal just before kick-off, gee-ing his teammates up as they lined up before walking out. As captain Fernandinho quietly led by example, it was Sterling doing the talking.
Pep Guardiola didn't look too pleased as he came in for half-time, and whatever was said at the break seemed to have made an impression as the players gathered in the tunnel before the second half.
As Fernandinho waited for the whole side to be ready, Rodri and De Bruyne took a moment to clarify some tactics for the second period.
Throughout the afternoon, there was plenty of friendly moments between the City and Chelsea squads.
Fernandinho was seen chatting with Chelsea captain Cesar Azpilicueta, while Rodri also caught up with his Spain teammate before Aymeric Laporte also joined the conversation. French pair Benjamin Mendy and N'Golo Kante shared an embrace, while former City goalkeeper Willy Caballero sought out some old teammates as he caught up with Phil Foden and Gabriel Jesus.
After full-time, Eric Garcia was seen chatting with Azpilicueta.
