“In many seasons there is a team who come through unexpectedly but not like this - not from bottom to top - it is truly amazing,” the West Ham boss wrote in The London Evening Standard about Leicester.
“They have some good candidates for the PFA Player of the Year. I am biased, of course, in favour of Dimitri Payet, who has been magnificent for us and has made a massive impact on the whole league but if he is not winning it, I would go for Vardy.
“Okay, Mahrez has been terrific and N’Golo Kante a revelation in midfield but Vardy epitomises Leicester’s incredible rise. It is not only his goals, it is his general work-rate. For defenders, he is a real pest!”
Vardy has been superb for Leicester so far this season and has been one of the best players in the Premier League.
The England international striker has scored 21 goals and created 45 chances in 33 Premier League appearances for the Foxes so far this campaign.
The 29-year-old has a pass accuracy of 65% and a shot accuracy of 58%, and has won 89 headers, 36 dribbles and 32 tackles.
Payet has scored nine goals and created 92 chances in 25 Premier League matches for West Ham so far this season.
The France international has a pass accuracy of 81% and a shot accuracy of 63%, and has won two headers, 62 dribbles and 15 tackles.
