Manchester United manager Ole Gunnar Solskjaer has revealed his fears after the Red Devils beat Paris-Saint Germain to kick off their Champions League campaign in style.
But Solskjaer must also now turn his thoughts towards ensuring qualification for next season's Champions League.
United have a run of big Premier League games coming up which, even at this early stage of the campaign, could prove pivotal to the Red Devils’ top-four chances.
Solskjaer's side host Chelsea on Saturday, then the Gunners eight days later, with the visit of Leipzig sandwiched in between.
The Red Devis must then travel to Turkey to play Istanbul Basaksehir before a trip to Goodison to face early Premier League leaders Everton ahead of next month's international break.
With all the ‘Big Six' sides having strengthened this summer, the battle for the top four spots looks set to be tougher than ever.
And the United boss knows every point could be vital both domestically and in Europe as his side face five big games in 15 days.
“We know that to get through we need 10 points to get through,” said Solskjaer of United's Champions League group.
“We have three, so next week's game against Leipzig is very important.
“Then we have Chelsea and Arsenal. There are so many games.”
