Gareth Bale said on Thursday he was "a bit behind" his new Real Madrid team-mates in terms of fitness, after a close season hampered by injury.
But the big-money signing from English Premier League side Tottenham said he hope to be back to his best as soon as possible and maintained that his troublesome foot was better.
"I feel good. I have been training in the last week with Wales. I have had two good sessions today and I got half an hour or 40 minutes game-time with Wales (on Tuesday)," the 24-year-old told reporters at the launch of Madrid's third kit.
"Obviously I am a bit behind physically than everyone else but I am hopeful I can catch up as soon as possible."
Bale signed for Real from the north London club earlier this month on a six-year deal for around Â£80 million ($124 million, 94 million euros).
The winger said he did not know whether Madrid coach Carlo Ancelotti would pick him for Saturday's game against Villarreal in La Liga.
"He has spoken to me but I think you will have to wait until the match later to see if whether I am picked or not," he said.
"Hopefully I can get my fitness up straight away and hopefully get a place in the team" he added, vowing to give "100 percent" regardless of where Ancelotti will play him.
Bale also said he was happy with the welcome he received in the dressing room, particularly from Portugal star Cristiano Ronaldo.
"It was amazing. He's a nice guy and he made me feel welcome just like everyone else," said Bale.
"I am just looking forward to getting on the pitch and doing well."
