"I think everybody has to defend," Matic said on the club website. "Football is a team sport.

"When you concede a goal, not only does the goalkeeper and defenders concede it, everyone needs to take responsibility. And also when we score everyone is involved.

"We have to start the action from the back – we defend together and we attack together.

"In my position my job is more to help give the balance to the team, especially when we defend, and we will all take responsibility."

United finished last season strongly, unbeaten in the league after the campaign resumed following lockdown, but the opening defeat to Palace put the focus on a relative lack of transfer activity as time ticks down in the window.

Solskjaer said earlier in the summer that he believed United needed to strengthen, but this week he has emphasised the quality he already has in his squad, saying he feels there is now greater competition for places than there was last term.

United started their season a week later than most, a result of their Europa League campaign only finishing in mid-August, a factor cited by Solskjaer as he said his side is still catching up in terms of fitness and form.

"The players are getting fitter and getting sharper and stronger, even though we're a few games behind the rest of them," he said. "In that respect, we hope to see an improvement and we probably need to, especially from the league games."

Sunday's match will pit Solskjaer against the man he replaced in Jose Mourinho. The Norwegian's season and a half have not brought trophies but there was a greater sense of optimism around United last season, even if that is now being tested by complaints over a lack of new arrivals.

Asked if he felt he had brought the club forward, Solskjaer said: "I'm not sure if I'm the best one to talk about progress or where we're at.

"I've had my view on what I wanted to do and I've had the backing from the club to go with my plan and vision. I think that we're all different.

"We've given young players a go and have also let many good players go. Other people can probably assess that progress. I'm enjoying working in this environment."
