England captain John Terry has backed his side to make it seven wins out of seven in qualification for next year's World Cup finals in South Africa.
Fabio Capello's side have taken maximum points from their opening four games in Group Six and Terry is hopeful of further successes against Ukraine, Kazakhstan and Belarus before the summer break.
He told reporters: "I think we can win all seven qualifiers this season.
"We have a good squad and some world-class players with teams who are doing ever so well in the Champions League.
"They are on fire and the good thing is they are also bringing that form into the England squad.
"The Ukraine match is massive ahead of the double-header in the summer. If we can win that and put another three points on the board, we will be well set.
"We will give them plenty of respect and the Slovakia game was good preparation as they are similar to Ukraine.
"Ukraine are a good side who are well-organised, but we are full of belief and the team is full of confidence at the moment."
Terry's team-mate, Gareth Barry, has also played up the significance of Wednesday's clash with Ukraine at Wembley.
He added: "We have started well with a 100 per cent record from our games so far. We can't ask for much more.
"But this game on Wednesday is massive, everyone in the squad realises that. Another win will give us a bit of breathing space.
"Saturday's game was a great warm-up for us and will have instilled confidence into the team.
"We will want to carry that on against Ukraine, but they are top-drawer and we will take nothing for granted."
