The north London club face a crucial fortnight in their pursuit of Champions League qualification and manager Andre Villas-Boas was hopeful that his top scorer this term would be fit to feature in a significant part of the run-in.
“It shouldn’t be as bad as it looks on the image,” said Villas-Boas. “There is a big, big possibility if we stay positive that he will be fit for the Manchester City game [on April 21] and it will only take him out of two games.
“We still have a big squad and the ability to adapt [without Bale]. We just have to play against Everton [in the Premier League at the weekend] and see when these players get back to make us even stronger.”
