Frank Lampard and Steven Gerrard know England will face a much sterner test when they take on Ukraine on Tuesday than in their World Cup qualification romp against Moldova.
Lampard netted the first two goals in the 5-0 win in Chisinau on Friday night, with Jermain Defoe, Leighton Baines and James Milner also on target in their Group H opener.
But Chelsea midfielder Lampard and Three Lions skipper Gerrard know Ukraine, who England narrowly defeated 1-0 at Euro 2012, will be a different proposition at Wembley.
Lampard, who missed the summer showpiece through injury, said: "Ukraine are a quality team, they showed that in glimpses in the game during the European Championship.
"It was a pretty impressive performance and a tough match for the team even though we got the win.
"They are certainly going to come to Wembley with intentions to make it difficult for us and show what they are about, so we will have to be on top form.
"We need to rest up, prepare right and try and keep the level of performance we are producing."
Gerrard, who set up Lampard's second goal on Friday night before exiting the action at the interval, said: "It will be a different test on Tuesday.
"With all due respect to Moldova, Ukraine are a fantastic team as they showed in the Euros. I'm sure it will be a lot tougher test."
