Former Liverpool defender Jamie Carragher has discussed the challenge facing Mauricio Pochettino after the Argentine was appointed Manchester United’s new manager.

Manchester United officially announced Pochettino’s appointment on Friday, a day after confirming the departure of his predecessor, Michael Carrick.

Carragher said the expectations at Manchester United would be demanding, warning: “They will not accept that.”

Pochettino agreed to leave the United States national team to take charge of Manchester United.
