Claudio Ranieri’s side are surprisingly top of the table with a third of the season already played and the United manager knows all about the threat Vardy poses after the England international scored in Leicester’s win over United last season.
Van Gaal said that Vardy, who equalled Ruud Van Nistelrooy’s record for scoring in 10 consecutive Premier League games last weekend, will be a tough customer to deal with.
“He was already last season a very nasty player for us,” he said.
“I remember Vardy in that game, so I don’t want to remember that game especially, because of the result but also the way we lost wasn’t good.
“Vardy scored, won a penalty, and now he is scoring 10 games in a row.
“I only know Dennis Bergkamp, as a player with me, who did the same with Ajax. It’s not so easy to do that.”
Despite Vardy’s exceptional form this season, Van Gaal was in no mood to forget about the role the Leicester striker played in the corresponding fixture last year, when he won a dubious penalty.
“That game [against Leicester], I said also in the press conference after, we lost because the referee gave a penalty, against Rafael, I remember that very well,” he said.
“In my opinion, he [the ref] changed the match, but of course it was still 3-2 then, so you cannot blame the ref you have to blame yourself, but it was the return of Leicester in that game.”
