Juan Mata knows Manchester United let down their away fans in defeat at Leicester City.
Writing on his blog, Mata, who came on for Angel di Maria 14 minutes from time, said: "After a whole week waiting for the match I could not imagine a Sunday like this.
"The way back from Leicester to Manchester on the bus seemed really long.
"I kept thinking about how we lost a game that was under control, but the thing is we were ahead, they equalised and when we tried to get advantage again we lost.
"It's really tough to score three goals away and come back home with no points.
"On our way back to Manchester I was thinking about what had happened and felt so disappointed as all those that came with us to the stadium.
"Honestly, I feel very sorry that the weekend ended up for our fans in such a sad way."
