Bale believes he has impressed in his first full season at White Hart Lane.
"He needed a run in the team, he got that and he's showed exactly what he can do this season," Bale told Spurs TV.
"He's played really well. He's set himself a benchmark this season and hopefully he can maintain it.
"Players know all about him now, they will be looking to stop those forward runs and he has to find a way around it - I'm sure he will."
