The Wales international has received widespread acclaim after another match-winning display as he scored twice in a 3-2 victory over West Ham United.
The 23-year-old has netted 15 goals in 23 Premier League appearances for Spurs, winning his side a valuable 15 points this term in their hunt for a fourth-place finish.
Unsurprisingly, Bale has been touted as one of the favourites to win the PFA Players’ Player of the Year award, but Wenger is adamant the Southampton youth star’s form cannot last forever.
“He has good pace, a good shot and his pace is an advantage to use with his shot,” said Wenger.
“And at the moment he has a good conversion rate between the chances he creates and the goals he scores. But that goes in cycles. No [he won’t play like this forever].
“To maintain that conversion rate, which I think is the best in Europe, is very, very difficult.”
Bale has scored four goals against Arsenal after completing a £7m move to Spurs from Southampton in 2007.
