The emerging feud between Eugenie Bouchard and Maria Sharapova shows no signs of fading any time soon, after the Russian took to Twitter to aim a fresh dig at her new-found rival.

Sharapova claimed to be above Bouchard's jibes, who branded the former world No 1 “a cheater” on her return to tennis after testing positive for meldonium last year, but the 30-year-old has now hit back.

In the wake of their thrilling Madrid Open showdown, from which the Canadian secured a 7-5 2-6 6-4 victory, Sharapova has now liked a mocked-up image of a Bouchard autobiography, titled “Insufferable: My Life So Far”.

The title is based on Sharapova’s own autobiography - which is due later in 2017 - called “Unstoppable: My Life So Far”.

This comes two days after Bouchard had taken aim at Sharapova with a not-so-subtle dig in the wake of the 23-year-old’s victory in Madrid.

Posting a photo of herself celebrating victory at Madrid’s ‘Magic Box’, with the caption “How bow dah”, Bouchard made her feelings toward her rival clear.

Earlier that day the current world No 258 revealed that her inspired display in Madrid, which saw her through to the third round of the tournament, was motivated not only by the need to back up her criticism of Sharapova, but to reward those within the sport “too” scared to speak out against the five-time Grand Slam champion.

"I definitely had some extra motivation going into today,” she said on Monday. “Obviously I had never beaten her before and also given the circumstances.

"I was actually quite inspired before the match because I had a lot of players coming up to me privately wishing me good luck.

"Players I don't normally speak to, getting a lot of texts from people in the tennis world that were just rooting for me.

"I wanted to do it for myself, but also all these people. I really felt support.

"It showed me that most people have my opinion, and they were just maybe scared to speak out."
