Tottenham Hotspur manager Jose Mourinho found himself chasing after Eric Dier and sure wasn't what he expected to be presented with on Tuesday night.
Mourinho immediately followed suit and the TV cameras showed the boss going into the changing rooms to look for Dier.
"Everyone can imagine!" Dier said after the game via BBC Sport.
"I am OK but that was a first for me. There was nothing I could do about it and when you've got to go, you've got to go. Some things you can't stop.
"I don't know if Jose understood what I was doing to begin with. I told Pierre-Emile Hojbjerg and Toby Alderweireld as I was going off, I simply had to go.
"I was struggling with stomach cramps, it had got too bad."
Dier eventually made his way back to the pitch together with Mourinho who didn't seem very pleased at the whole situation.
Dier continued: "Jose wasn't happy but there was nothing I could do about it, nature was calling."
'I understood what was happening - I went to try to make it happen faster'
"What happened to Eric Dier is not normal, I have to praise him in a special way," said Mourinho.
"It should be forbidden for a player to play two games in 48 hours at this level [after he played against Newcastle on Sunday]. What he did is not human to do.
"He had to go - he had no choice. Maybe it is a normal thing when you are completely dehydrated, which is the case. I had to put pressure on him to get back but he is a great example for everybody."
Mourinho said: "When Dier went off I understood immediately what was happening, I went there to try to make it happen faster, to put pressure on him.
"It is a consequence of his physical state, he had no energy in his muscles. I don't want to believe that we have another week like this one.
"If the authorities don't care about players, I care."
