Ole Gunnar Solskjaer blamed Manchester United's tough fixture list for their 0-0 draw with Chelsea on Saturday but claimed his side would have won if there were fans in the ground.
The Red Devils were held by the Blues four days after their memorable win over Paris Saint-Germain in the Champions League group stages, though Solskjaer's side had the better chances.
Blues goalkeeper Edouard Mendy pulled off two stunning save to deny Marcus Rashford in both halves, while United debutant Edinson Cavani had a goalbound effort blocked by Thiago Silva.
