A late Cristiano Ronaldo winner capped another Manchester United comeback in the Champions League Wednesday, this time against Atalanta, as holders Chelsea and Bayern Munich cruised to big victories and Barcelona gave their campaign a shot in the arm.
The knives were out for United manager Ole Gunnar Solskjaer as his side found themselves 2-0 down at half-time at Old Trafford, Mario Pasalic and Turkish center-back Merih Demiral scoring for Atalanta.
However Marcus Rashford made up for missing a glorious chance just before the interval by pulling a goal back eight minutes into the second half and sparking another remarkable fightback.

After losing to Juventus last time out, Chelsea got their defence of the trophy back on track as Jorginho scored two penalties in a 4-0 drubbing of Malmo in the rain at Stamford Bridge.
However, their evening was marred by an injury to Romelu Lukaku, who hobbled off after being hurt winning the first penalty of the night midway through the first half.
Andreas Christensen had given Chelsea the lead before that. Kai Havertz scored Chelsea's other goal, but Thomas Tuchel's side also saw Timo Werner come off before the break.
