"Dimitar was always going to be going," admitted the boss. "I said last year he'd be leaving at the end of the season. He's not gone yet, though. I don't know anything about it. We've not had any contact with him.
"We thought he was in Italy, going to Fiorentina. But it turns out he's not gone there. He could be anywhere, to be honest with you. It wouldn't surprise me if he's at Tottenham.
"I don't think he's certain to go to Fulham, put it that way. He's a very talented player and his contribution is good, particularly at home. He's the only player to score a hat-trick against Liverpool for United. When we changed our game, it didn't suit him. We started to play with more speed. Wherever he goes, he'll do well."
There is unlikely to be any other activity around Old Trafford before the deadline on Friday night.
"There will not be any more business today," stressed Sir Alex. "There's no need to loan today. We can do that seven days after the deadline. There are one or two players we need to get out on loan - younger players - but we don't have to make a decision on that at the moment."
