Ole Gunnar Solskjaer has warned his Manchester United players that there will be no room for the cheap errors that have cost them of late as the manager vowed to go full throttle at Leicester City tomorrow.
Paul Pogba's deliberate handball cost United a penalty in Wednesday's 1-1 draw against West Ham, while lax marking by Victor Lindelof and Harry Maguire allowed Southampton to claim a 97th-minute equaliser the previous week.
Sandwiched between was an error-strewn display from goalkeeper David de Gea in the dismal 3-0 FA Cup defeat by Chelsea at Wembley last Sunday.
It has left United requiring a point at the King Power Stadium to guarantee qualification for next season's Champions League.
Yet Solskjaer has ruled out any prospect of a safety-first approach as he urged his players to cut out their concentration lapses.
"Focus and concentration is vital in football," the United manager said. "When you play against quality teams and quality players, one lapse of concentration can hurt you.
"We have given ourselves a good chance of being in the Champions League but we can't go into the game thinking about what the outcome could be.
"We've just got to perform at a high enough level and standard so we can get a result."
Failure to beat Leicester would mean the club recording their lowest points tally in the Premier League, even if that would still be enough to secure a top-four spot should Chelsea lose at home to Wolves.
But Solskjaer is convinced his side are on the right path.
He said: "We've come a long way mentally. We have shown more robustness, resilience when we lost the first goal in games and we've also shown the heights when everything's flowing.
"I'm delighted with how the development looks. We've had some hard times, some setbacks, but we've shown that this is a team going places and if we can finish the season with a trophy in Europe and third (place in the league) then we can discuss that (what is acceptable for Manchester United).
"If we get a result against Leicester, everyone would say this journey has been a good one but then if you get there, it's not like we can breathe and relax.
"We know there are two teams too far ahead of us so we have to step it up even more."
Solskjaer will give Eric Bailly and Luke Shaw time to prove their fitness after the former missed the midweek draw with West Ham after sustaining a head injury in the FA Cup semi-final loss to Chelsea, while left-back Shaw has missed three matches with an ankle complaint. (© Daily Telegraph, London)
