FC Utrecht captain Willem Janssen has offered Manchester United players an insight on what to expect from Erik ten Hag.

Janssen, who played under Ajax coach Ten Hag for two-and-a-half years at FC Utrecht between 2015 and 2017, said that his former coach revolutionised that club and expects the Dutchman to do the same at United.

Janssen told the Mirror: "He's very professional, he's highly demanding. He demands everything from a player. He creates a winning environment, every detail is key.

"When he came to Utrecht, the mentality changed. It needed some time, three or four months, before the mentality of all the club and the players changed a lot because of him.

"He taught us to be more professional, more active, more concerned about your own development and the team's development. In a way, he was a very complete manager."

Taking inspiration from Pep Guardiola's training methods, Ten Hag is said to also be an exponent drawing lines on training pitches to make players more aware of space and key areas of the pitch.

Janssen said: "There were many more lines and everyone was asking: 'Eh? What's this?'

"And then he talked about half spaces, to learn how to be more compact as a team. It was a moment where we didn't know what was going on, but he explained and we used it a lot in training sessions.

"After his arrival, the results improved, we finished fifth, fourth and fifth. For the club, it was a very successful period."
