Bale came to Tottenham's rescue once again last night by scoring two sensational free-kicks to hand Andre Villas-Boas' men a 2-1 victory over Lyon in the Europa League.
Without the 15 goals scored by the in-form Welshman, Spurs would sit 10th in the Barclays Premier League, rather than fourth.
Two seasons ago Bale had the world at his feet when he made a mockery of Inter Milan's Maicon at White Hart Lane, but his game has come on hugely since. He has become quicker, more powerful and his shooting skills rank among the best in the league.
The former Southampton man, who has also learned how to operate as up front under Villas-Boas this term, is now being talked about as one of the best players in the world, but at just 23-years-old, he insists there is more to come from his game yet.
"It's probably the best I've been playing so far in my career, but I've still got room for improvement," Bale said after the 2-1 win.
"Season after season I have to improve in all areas. I just want to keep doing that, keep working hard and, hopefully, keep getting better.
"I've just got to keep my head down, keep working hard, keep trying to keep my form."
