Leicester City striker Jamie Vardy should start ahead of Wayne Rooney for England at Euro 2016, according to Foxes assistant manager Craig Shakespeare.
Vardy, 29, has been in scintillating form this season, scoring 19 Premier League goals and netting his first international strike in Saturday's 3-2 win over Germany.
England captain Rooney, who has 109 caps and 51 goals to his name, is currently injured, and the Manchester United forward has struggled to impress this season.
Vardy's displays have led to debate over whether he should be selected over Rooney by Three Lions boss Roy Hodgson at this summer's tournament in France.
Ahead of Tuesday night's friendly with Netherlands, Shakespeare told BBC Radio 5 live's Daily programme: "For me, he's a certainty to go to Euro 2016 and a certainty to play. He must be a nightmare to play against.
"I would love to be in a position to choose between him and Rooney. My money, at the moment, would go to Jamie purely on form.
"When we brought him to Leicester we told him he had the attributes to go as far as he wanted. I don't think he really believed it.
"We've seen him go from strength to strength, and I'd love to see him play down the middle for England in the Euros and actually do something for his country.
"By that I mean get as far as we possibly can."
Meanwhile, Rooney has been backed by international teammate Ross Barkley, who said he helps England's younger players by passing on his experience.
