The former Fleetwood Town striker is currently undertaking a dream campaign with the Foxes, scoring 12 goals in 12 league matches and at least one in his last nine straight league games.
Watford were the latest team unable to stop the 28-year-old from finding the net, losing 2-1 on Saturday.
And Hornets boss Sanchez was very respectful after the game in praising his side’s opponent, saying: “Vardy? He is amazing. He’s the best striker at the moment.”
“He is always willing to run and play and get behind the back of the defensive line. He is very difficult to stop.’ Can he can find the net at international level? ‘I have no doubts. For sure.”
Vardy’s record has already cemented his name in the Premier League’s history books as he became the first English player to score at least one goal in nine consecutive league matches.
Former Manchester United star Ruud van Nistelrooy holds the record at ten, though the Dutchman’s accomplishments were done over two campaigns unlike Leicester’s leading scorer.
The question now for Vardy is whether he can replicate his form on the international stage. So far in England colours he has struggled to make an impact, though playing out wide hasn’t helped.
There have been plenty of calls from supporters to select Vardy in his favoured central spot, though with Harry Kane and Wayne Rooney for options the competition for that role is extremely strong.
