Jose Mourinho has attempted to put his finger on why Manchester United have flattered to deceive post the successful Sir Alex Ferguson era.

The famous club have dropped off the pace in the Premier League since Ferguson ended his time as Red Devils manager with a Premier League title in 2013.

David Moyes, Louis van Gaal (2016 FA Cup), and Mourinho (this season's EFL Cup), have tried valiantly to restore United's glory days which the latter admits has been difficult due to the ever-changing landscape of football in England.

"I arrived at Manchester United at a difficult time. But it was the same for David Moyes and Louis van Gaal," Mourinho told France Football.

"The period that followed the departure of Sir Alex was difficult to handle for the club, and not only because of his departure.

"It was also a new era for English football. A time where the financial strength became so enormous that it became terrifying for everyone. Because this financial strength did not exist only among two clubs, like in Spain, not among one club like in Germany, not among one or two clubs like in France.

"In England, it is spread out.

"So yes, there are more powerful clubs than others and the expectations that come with that. But, here, everyone is powerful now. The scenery has changed.

"If I want to buy a player from Tottenham, I can't. Nor can I buy a player from Manchester City or Arsenal. That was not the case before.

"At Chelsea, I brought in Shaun Wright-Phillips, who was the best player at Manchester City or Ashley Cole from Arsenal. Sir Alex, when he wanted the best player from Tottenham, he bought Michael Carrick and then Berbatov."
