Gary Neville has claimed that Jamie Vardy's quality will be tested when the Leicester City striker faces "top defences" in the coming weeks.
The 28-year-old equalled Ruud van Nistelrooy's record of scoring in 10 consecutive Premier League goals in Saturday's 3-0 win over Newcastle United at St James' Park.
Vardy has scored 13 league goals this season, but Neville believes that he will need to prove how good he is when teams begin to show him more respect.
"There are questions we have to ask moving forward about Vardy because there's no way teams will be as bad as Newcastle's defence were on Saturday," Neville said on Sky Sports' Monday Night Football show. "He's going to get marked tighter and he'll have less space.
"Sometimes players like Jamie Vardy can become a little bit exposed because you always think of them running in behind but he's got a good touch, a much better touch than people give him credit for.
"I think he can play in tight areas but I think in the next few weeks against the top defences is where we'll really see whether he can adapt and adjust when other teams will give him a lot more respect than other teams are at the moment."
Leicester, who are currently at the top of the Premier League table, will face Manchester United, Chelsea, Liverpool and Manchester City within their next six games.
