Lingard is coming off the back of an impressive season with Man Utd, scoring 13 goals and providing seven assists in 48 appearances in all competitions.
"People always questioned, "is he going to be big enough, is he going to be strong enough", but when you have the intelligence and game management that this kid's got, you can be two foot tall and get through".
England's attack has looked menacing in their opening two games and it has to be said that Lingard has been a standout player.
"We know what we're up against, we know the players inside and out and know what we've got to do". The Tottenham Hotspur striker said England fans were justified in dreaming of winning the World Cup for the first time since 1966. "We missed out on that opportunity but it would be harsh to criticize the players after a day like that, in the heat as well, so we must enjoy the win".
Lingard made it three with a superb curling strike after a well-worked England move, before Stones got his second, pouncing on a loose ball after Raheem Sterling's effort had been blocked.
However much they tried, Panama struggled to block England's route to goal.
Kane didn't have to wait long to add to his tally, converting from the penalty spot in the 22nd after Lingard was brought down by Fidel Escobar.
Chasing the golden boot, Kane relied on his heel to complete his hat trick by getting the faintest of touches to divert Ruben Loftus-Cheek's shot into the net. Portugal, oddly, scored only one goal in the first half and six in the second - and then did not score again for the rest of the tournament, knocked out in the round of 16 by Spain.
