Ole Gunnar Solskjaer has brought the smiles back to people's faces and knows exactly what the club is about, according to Luke Shaw.
The United full-back has started 10 of 11 Premier League games under Solskjaer with United putting together an unbeaten league run which has catapulted them back into top-four contention.
"The whole mood of the camp is the best since I've been here," Shaw told Soccer Saturday.
"The results are showing that with the right mood and mentality. The way the coaches and managers are putting their tactics out on the pitch are working perfectly right now. Of course, it could have been better if we beat Liverpool and against PSG, but there are lots of positives to take at the moment. It's onwards and upwards at the moment - we're happy with how things are going. We need to keep doing that."
Solskjaer replaced Jose Mourinho in December, who Shaw had an edgy relationship with.
Shaw had previously struggled to earn a place in Mourinho's side at United, with the Portuguese manager on one occasion saying he was asking to be substituted because he was playing so badly.
The England full-back has seemingly responded well to Mourinho's tough love though and admits he couldn't be happier with how life is currently under Solskjaer.
"He [Solskjaer] knows what this club needs and what it's about," he said.
"He's brought the enjoyment back and there are happy faces around. He's brought the right and good football back here and we're all enjoying it."
