Jose Mourinho has come underfire for his team selection and late substitutions in Tottenham Hotspur's 2-1 loss to Manchester United at Old Trafford.
It was the Portuguese's first chance to return to his old stomping ground as an opposition manager and according to some Spurs fans he made a key error in not starting Tanguy Ndombele and waiting too late to bring on Giovani Lo Celso.
Rather than trust the two summer signings who were purchase under Mauricio Pochettino to play a larger role in his plans, he left both on the bench until the second half.
Christian Eriksen was used ahead of the pair despite concerns over his commitment and future with his contract set to run out at the end of the season.
Harry Winks and Moussa Sissoko were deployed behind the Dane with the Frenchman giving away the penalty that allowed Marcus Rashford to score the winner.
After winning his first three games in charge as Tottenham boss, Mourinho suffered the first defeat of his reign away at Old Trafford against United.
Ole Gunnar Solskjaer, the caretaker boss turned manager who replaced him, won himself a reprieve from the scrutiny over his own future at the club.
Fans took to Twitter to vent over the team selection decisions that they felt cost Spurs the game.
Lo Celso is only on loan from Real Betis this season but there are understood to be clauses in the deal that saw the Argentinian join Tottenham in the summer.
He could see his move converted into a permanent switch to Spurs, although there has been speculation over his interest in the project without Pochettino.
Ndombele, meanwhile, has struggled to find his full fitness so far in England since leaving Ligue 1 side Lyon in the summer.
Tottenham won the race to sign the Frenchman, who was one of the most coveted players in Europe after stand out performances in the Champions League, most notably against Manchester City.
Already well on his way to becoming a fan favourite, he was hailed as the natural successor to Mousa Dembele as the new box-to-box force that Spurs had been lacking.
He has already shown glimpses as to why that comparison was apt in his early months at Hotspur Way.
