A stunning strike from Marcus Rashford and a Danny Welbeck header sparked a confident-looking England to a 2-0 win over Costa Rica in their pre-World Cup friendly at Elland Road.
Rashford, who impressed throughout with his speed and control, fired England ahead in the 13th minute, unleashing a dipping diagonal drive from the right which flew past helpless Costa Rica keeper Keylor Navas.
England, whose manager Gareth Southgate made 10 changes from the side which beat Nigeria 2-1 at Wembley on Saturday, dominated possession against a mostly unadventurous Costa Rica but created few clear chances on Thursday.
After the break, Jordan Henderson forced a fine save out of Navas with a blast from the edge of the box and defender Harry Maguire had a header cleared off the line by Bryan Oviedo.
The win was wrapped up in the 76th minute when substitute Welbeck, for some a surprise choice in England's World Cup squad, stooped to head in a Dele Alli cross.
"I feel in good physical form leading up to the tournament. I still need to get in the box a bit more to finish off chances. It means a lot to be involved but going to the World Cup and playing a major part in my main aim," said the 20-year-old Rashford.
"We have got a good chance. Anything is possible and we have to go there with the highest expectations."
England start their World Cup Group G campaign in Russia against Tunisia on June 18, while Costa Rica open against Serbia, a day earlier, in Group E.
Portugal, meanwhile, beat Algeria 3-0 with Goncalo Guedes netting a brace and Bruno Fernandes completing the scoring.
Guedes, with nine appearances and one goal before Thursday, fired Portugal in the front in the 17th minute after William Carvalho hit a long ball over the Algeria defence and the lively Bernando Silva cushioned a header invitingly into his path.
Ronaldo set up the second in the 37th minute when he sped down the left and provided a pinpoint cross which Fernandes met with a powerful downward header for his first international goal.
A similar move led to the third goal as Raphael Guerreiro burst down the left and Guedes met his cross with a bullet header into the roof of the net in the 55th minute.
"There were some good things and a lot to improve, but the first 20 minutes were very good," said coach Santos, who refused to give anything away about his starting line-up.
"The 23 are all ready to play, that is the most important thing."
