Louis van Gaal has described Jamie Vardy as "a nasty player" for Manchester United and has compared the Leicester City striker's goalscoring run to that of Dennis Bergkamp.

The England international drew level with Ruud van Nistelrooy's Premier League record of scoring in 10 consecutive matches when he netted in the 3-0 win over Newcastle United last weekend.

Vardy won a penalty and scored the final goal in Leicester's shock 5-3 win over United last season at the King Power Stadium and Van Gaal is wary of the danger posed by the 28-year-old ahead of the Foxes' trip to Old Trafford this weekend.

"He was already last year a very nasty player for us. He scores, he provoked a penalty and now he is scoring in a row 10 goals so now you are a great player," Van Gaal said on Friday. 

"I only know, for example, Dennis Bergkamp as a player with me did the same with Ajax and that is not so easy."

When asked if Vardy was a potential January transfer target, Van Gaal added: "That's none of your business."
