More so than anything, he has no right to go up to Redmond as a player and start screaming at him for time-wasting. They are employees doing their jobs who take instructions from the manager, if he has a problem with the time-wasting why not have a quiet word with Pellegrino when he shakes his hand at FT instead of screaming at one of the players who's just doing - as the whole team is - what they're told to do?
Also feck knows why he had such a problem with the time-wasting specifically. It all got accounted for and they got 6 minutes of injury time and a 2nd goal and the 3 points as a result! You can understand if there were only 2 minutes of added time or something, but no, they got the full amount and got the win.
Just go and celebrate ffs, any sane manager would be expressing their emotion positively at that moment, they're come through a tough game with a last gasp winner.
He's definitely got a few screws loose.
