Despite only appearing as a late substitute in Donetsk, the Arsenal attacker is prepared to take his chance, as the Three Lions settled into the European Championship with a draw against France.
"I am excited for Friday night," he told the Football Association's website.
"The game the other day was always going to be tough. A draw was a good start, but you can always improve.
"We have to score more goals because we don’t concede many. We are training very hard and the manager and staff have been great with all the preparation. We just have to make sure we do it for the fans on Friday and get the win.
"It is a solid start. Ukraine will be tough when we come to that game as well. We just have to think we need to win the next two games and don’t worry about anyone else, but we will make sure we are ready."
Based in Krakow, Walcott insists that despite having to travel to Kiev to face Sweden in Ukraine, the squad are settling in extremely well.
"The lads are in the game room after lunch and dinner playing table tennis, Fifa, snooker - it's all happening," he added.
|THEO ON TARGET?

"I am not bad on Fifa but I have gone to the table tennis, I am jumping from one and two seed.
"It is quite important for the team to be together before the matches to prepare well. It is trying to make it as normal as possible like it as club level. It is working and it is going quite well.
"A lot of people seem to forget what goes on in the background. Everything is done for us here, we are well treated, people will never see that. We have to thank them as well. They are all great. I don’t want to leave anyone out but everyone here is fantastic."
