Pep Guardiola said he would need a nap to talk about Manchester United's many rumoured managers amid mounting speculation regarding potential new Red Devils boss Ralf Rangnick.

Rangnick is reportedly set to take over United on an interim basis following the sacking of Ole Gunnar Solskjaer, with a potentially longer stay at Old Trafford in a role behind the scenes.

Former RB Leipzig head coach Rangnick – who also held various roles at the Bundesliga outfit across eight seasons – is currently head of sports and development at Russian side Lokomotiv Moscow.

Talk of Rangnick's six-month appointment has dominated headlines as United reportedly eye long-term targets Mauricio Pochettino of Paris Saint-Germain and Ajax's Erik ten Hag, while Sporting CP boss Ruben Amorim has also been mentioned.

Manchester City manager Guardiola was asked about the potential arrival of Rangnick in the Premier League.

"Personally? No," Guardiola said when asked if he knew much about Rangnick. "I spoke once to him in my lifetime by phone.

"I never met him, but I know he did an incredible job in an organisation like Red Bull Leipzig and Salzburg and has big experience in Germany, is incredibly well known. But personally, I haven't met him."

Further pressed on Rangnick and Lars Kornetka, who worked alongside Guardiola at Bundesliga champions Bayern Munich as an analyst, the Spaniard dismissed the reports.

"Listen, listen, over the last 10 days, maybe it was 20 names of a possible manager for Man United, so I cannot speak for each one," Guardiola said ahead of Sunday's clash with West Ham.

"Maybe this afternoon we'll have to take a nap, so we'll spend three hours to answer all the possible candidates to be Man United [manager]. So at the moment he will be appointed, if you ask me the opinion, I will give my answer.

"So no, I don't know. Now Michael Carrick is the [interim] manager for Man United, and that is my only concern."

Defending champions City are second in the table, three points behind leaders Chelsea through 12 rounds, while United are 12 points off the pace.
