Paul Merson wondered if the track record of Ralf Rangnick made him the right person to turn around Manchester United's fortunes.
The team is currently under the guidance of Michael Carrick, who is expected to be named interim manager. At the end of the season, he will become a consultant when United hire a long-term boss.
Sky Sports pundit Merson believes the challenge at United is different to anything he's faced before, despite the fact that Rangnick has overseen the rise of clubs such as Hoffenheim and RB Leipzig through the German league.
They need an interim manager. Merson told Soccer Saturday that they don't know what they're doing.
If it wasn't for two goals in the last minute atWatford, Ole would be at the club today. I don't think there was a plan. They didn't think it would end up like that. I think he's still in charge on Sunday. I think they were going to keep going.
He's never managed one of the top teams in the world and I'm hearing people say he's great, but he's never managed in England. Why is that happening? When managers have been up, why hasn't anyone else come in for him?
I hear great things about him, people say he's going to press and he's hard working, he's turned lesser teams into real contender. Getting a Hoffenheim or a Schalke to a certain stage is a lot different.
"When you're asked to go to one of the biggest clubs in the world and they already have superstars and you have to make them play, it's all right at Hoffenheim and Schalke because they want to get there." You have to get these players to leave.
This is going to be a lot harder than people think.
I'm hearing that he'll come in and that will be it. Man Utd are lucky. I'm not sure.
The recent performances of the United players during defeats to Manchester City,Liverpool andWatford would make it difficult for a manager to coach them.
He said that Man City was embarrassing. It wasn't as bad as Man City, and then it was a joke.

"At the end of the day, we can all say 'Solskjaer, Solskjaer' but it's the players who cross the line, they have to play the game."
If the players aren't running around, it doesn't matter what you're doing on the bench.
There is a problem with the Pochettino.
Merson is uncertain about how that appointment could play out, as Mauricio Pochettino is the favourite to be given the reins at United next summer.
Merson says the performances of Paris St-Germain this season could complicate matters for Mauricio Pochettino, who is currently in charge of the French club.
Man United fans will be asking why they want Pochettino if he doesn't win the trophy. He has a squad of players at Paris Saint-Germain who are some of the best in the world, but you haven't won the European Championship?
If you win the European Championship for the first time ever, then you want to keep him there for the next three, four years, because you want to dominate the competition for the next three, four years.
Expect a 'whirlwind' impact from Rangnick at Man Utd.
