Jones praised Galatasaray's fans for making so much noise during their 1-0 win.
"It's the best [atmosphere] I've ever played in," he told manutd.com. "From start to finish. I couldn't hear the keeper. I couldn't pass messages on. It was very difficult but the same for both teams.
"We should have switched on and dealt with the corner. We shouldn't be getting punished on set-pieces. It's happened and we still had chances to go on and draw, if not win, but it just wasn't our night. There were a lot of positives. We controlled a lot of the play - we were lacking a bit with the final cross or final ball and perhaps should have finished it off. But I think we were a bit unfortunate."
