Igor Tudor's decision to substitute Antonin Kinsky early against Atletico Madrid was "disgraceful" and he "should have resigned after the match", says European football expert Julien Laurens.
The Tottenham boss has come in for heavy criticism for his decision to take the goalkeeper off after 17 minutes after early errors during the 5-2 defeat in the Champions League on Tuesday.
Discussing the incident and Tudor's time in charge so far on BBC Radio 5 Live's Euro Leagues podcast, Laurens said: "Adds insult to injury [not seeing him off the pitch]. I think it was disgraceful what he did. And it was [Cristian] Romero who told Tudor to take him off, it wasn't even Tudor's decision.
"I'm so disappointed with Tudor since he has arrived – it has been mistake after mistake. He should have resigned after the match. It was another humiliation, like Arsenal, like Crystal Palace. It is a lot of humiliation when you have only been in charge four games.
"I know it is only until the end of the season, but he is on course to be one the worst managers we have ever seen in the Premier League."
Italian football writer James Horncastle shared a similar view, adding: "I've followed his [Tudor's] career in Italy and I've never seen him take action like that – so drastic. Something that is not only damaging to Kinsky but also him. It will be the decision he is most associated with in his Tottenham career.
"It is very hard to expect him to turn it around at Tottenham now. But that is the big surprise for me. Even though he hasn't had Premier League experience, he has had experience of these kinds of situations. To see him flounder and make mistakes nearly every game has been very disappointing."
However, Spanish football expert Guillem Balague felt the ex-Juventus manager was right in his decision.
"When two mistakes happen in quick succession, sportspeople can go through analysis paralysis, which means the goalkeeper in this case stops acting automatically and he begins to over think and then another mistake can happen," he said.
"If Tudor saw this then he has got to get him out."
