Bale returned from a foot injury for Sunday's 1-1 draw with West Ham and said: "It has been a bit frustrating sitting on the sidelines, I did my foot in the Newcastle game and it took longer than I expected to recover.
"It was badly bruised on the bone and that takes a long time to heal - I am just happy to be back now.
"I think personally I could have done a bit better. It was a my first game back and I felt it a bit. It could take a little while for me to get back in the flow, but hopefully will be operating fully soon.
"It was unlucky not to win, but that is football and it didn't go our way. We are looking brighter now as a team though and we can look forward to the rest of the season."
