England midfielder Jack Wilshere has declared himself fit for what he concedes will be the biggest game of his international career.
Wilshere may only have eight caps, but he is already considered one of the most capable players in the England squad - thanks mainly to his exquisite talent and also because of a lack of strength in depth within the ranks.
Wilshere made his return from an ankle injury in October 2012, but England and Arsenal fans have only seen glimpses of the star since, with Arsene Wenger keen to ease the 21-year-old back in to action for fear of another setback.
He has only completed three of the seven games he has played so far this season and England boss Roy Hodgson removed the midfielder, who was suffering from a stomach bug last week, in the second half of the 4-0 win over Moldova on Friday.
The crowd agonised every time the Moldovans kicked out at Wilshere knowing another injury could put paid to his chances of starting against Ukraine on Tuesday, but he insists he is fully fit for the crunch game in Kiev.
"Yes, I'll be okay. I felt good," the Arsenal man said after the victory.
"I had a bug last week and that took my energy away a little bit so the idea was to get an hour under my belt and I felt good.
"That will do me well for Tuesday."
Had it not been for a number of serious injuries, Wilshere would have amassed four, maybe five times the number of caps he already has.
Friday's game was his first appearance in England's World Cup qualifying campaign, with the majority of his caps coming in friendlies.
Although he has lined up for England against Brazil and France, he knows the biggest test of his international career will come when England travel to Ukraine on Tuesday.
The stakes are high in Kiev, with England knowing victory would send them three points clear of second-place Montenegro with two games left.
"It will be the biggest (international game) I have played in," the Arsenal midfielder said.
"It will be a harder game than the Moldova one, we know that. They have got some dangerous players, as we saw when they came to Wembley and drew so we have to be ready. It's going to be a tough game."
As Wilshere points out, Ukraine showed they are no pushovers when they came to London 12 months ago.
The Three Lions needed an 88th-minute penalty to snatch a draw against the visitors, who took a first-half lead through Yevhen Konoplyanka.
The last time England played a qualifier in Ukraine was in 2009 when the team lost 1-0 in a hostile atmosphere which boiled over at times, with the game being stopped on one occasion to clear flares from behind Rob Green's goal.
Wilshere expects a similar atmosphere on Tuesday, but he thinks England have enough wise heads to deal with the pressure.
"I think we have got players who play in the Champions League so obviously we will be ready for that," he said.
"We have some great experience in this team.
"If we win we will put ourselves in a very strong position going in to the last two games, which are both at home, so it will be nice to get an away win."
Wilshere was just seven years old when Frank Lampard made his England debut, but he is expected to line up alongside the Chelsea midfielder on Tuesday for what will be his 100th appearance at international level.
The duo worked well in tandem with man of the match Steven Gerrard on Friday and Wilshere was somewhat in awe of the company he had at Wembley.
"I have grown up watching Frank Lampard and Steven Gerrard play so it was a pleasure to play alongside them," Wilshere added.
"It worked well. Me and Lamps were playing higher and Gerrard was playing a deeper role. That suits him because his passing range is great."
