Mourinho was sacked on Tuesday, following a turbulent start to the season, which culminated in last Sunday’s 3-1 defeat at Anfield.
Sanchez has missed the last six games with a hamstring injury and has been recouperating in Chile, ahead of his likely comeback at the start of next month.
Sanchez tweeted: “This is FALSE!!! José gave me the chance to play for the best team in the world and I only have gratitude for him.
“We are a truly United team. We are MANCHESTER UNITED. Respect. I can’t wait to help the team !. Good luck tomorrow family!” SHARE THIS STORY USING ANY OF THE BUTTON BELOW ⬇ PLACE YOUR TEXT ADVERT BELOW ⬇⬇⬇
