Manchester United legend Roy Keane insists fans shouldn't panic after their poor defeat at Champions League opponents FC Basle.
Keane believes Jose Mourinho's first-choice XI is as strong as any team in Europe.
"The big plus for United was that their form has been that good in the Champions League that they gave themselves room to slip up," declared Keane to ITV.
“It was a weakened team. There were five or six players in that team will not be in United's strongest team. Mourinho will be looking at the bigger picture; forget about tonight and move on. They will be competing to win this title, without a doubt.
“When lads come back to full fitness, Manchester United will compete with all the top teams, for sure."
Keane went on to suggest United dropped into a comfort zone as they went into a game knowing a draw would be enough to secure progress to the next phase, as the Irishman offered up excuses for his former club.
“The players are intelligent enough to know that the draw (in Basel) would have one them and they started dropping deeper," he added.
“Basel grew in confidence and deserved it on the second half performance, but United were guilty a lot of chances. And it was a game they let slip, but they still have more than enough in their locker to win the last home game."
