Manchester United legend Gary Neville feels Jose Mourinho has improved the attitude of the players since his arrival.
After their win over Tottenham, Neville has been impressed at how Mourinho has turned United into a rock at the back.
"The one thing about this Manchester United team is that they are a really resilient unit," Neville told Sky Sports.
"One thing you can't criticise them for is their attitude. They are tough to beat.
“It's 36 games now unbeaten at Old Trafford - that's one hell of a record.
“A lot of clean sheets - they've got something going. There are a lot of positives.
"Mourinho set up to win the game today with two up top - which surprised us. He went for it.
“It was a struggle of a game but it was one they needed to win. There was pressure on United."
