in July, came on in the 97th minute and scored a last-minute equaliser in extra time before Los Angeles beat Philadelphia Union on penalties to win the MLS Cup for the first time on Sunday.

"It's been a difficult transition, trying to catch up, it's been difficult, especially with relocating with my family,"

Bale said in a press conference.

"I've tried to stay as fit as I can, to help the team on and off the pitch, it's all worth it when you have moments like today. The most important thing was the target to win the MLS Cup, we've done that.”

Wales start their World Cup campaign against United States on November 21. They then will play against Iran and England.

Bale added:

”I'm feeling better and better as time goes on. I've had a few setbacks, a slight knock a few weeks ago that kept me out for 10 days.

"It's been difficult mentally, leading into the World Cup – you see so many players dropping out, missing the World Cup.

"So it has been difficult mentally, I'm sure it has been for a lot of players, leading into this World Cup, so for sure it's been in the back of my mind trying to make sure I'm a 100 per cent fit.

"I felt good enough to come on and help the team, and happy to see us lift the trophy."

About his physical condition Bale said:

"I'm not 100 per cent at the moment, still coming back, have a few little issues like most players do, but we spoke about, that if I was needed for the last 20, 30 minutes, then I'm available.

"I was able to come on and give as much as I can, glad I came up with the goal. That's what I'm here to do, I guess."
