BRITISH tennis No.1 Andy Murray is finally back to his best after an injury-plagued and frustrating 2014 - and now he’s on the verge of rediscovering his best form, according to mum Judy.

It has been a dynamic start to the new season for Murray. His win against Spaniard Feliciano Lopez last month was enough to see him pass Tim Henman for the most wins by a British player in the open era – the 497th of his career at the BNP Paribas Open in Indian Wells.

Murray was also a beaten finalist in this year's Australian Open, losing to world No.1 Novak Djokovic in January. He is now second highest points scorer on the ATP Tour this year.

Judy – captain of the women’s Fed Cup team – is convinced a back operation in late 2013 severely hampered her son’s performances over the last 12 months.

She feels that Andy, who is marrying Kim Sears on April 11 in Dunblane Cathedral, is only just starting to move as he did in 2013 when he lifted the Wimbledon title.

She was speaking at the SSE Wembley Arena as a mentor for SSE's Next Generation programme, which provides vital financial and development support to 100 young athletes from across the UK and Ireland.

“I think when it's in your back it takes a long time to get to the stage where you can put it through what you need to,” she said.

“I think we saw some of his best tennis again at Indian Wells, which was great to see.”

Murray is hopeful of adding to his coaching team this week; with the appointment of former world number four Jon Bjorkman. The Swede will join as an assistant to Amelie Mauresmo.

Judy has called on fans to be patient as Murray rebuilds his career; and she is convinced another major title is just around the corner.

“Growing up, we trained a lot on clay in Barcelona,” she said. “He played a lot on hard courts in Scotland, albeit indoors, so that will always be, in my opinion, his best surface.

“The grass season is very short and fewer of the top players do well on grass because they don't have grass courts in their country.

“So I think grass always presents itself a big opportunity for any British player.

“But I think Andy’s goal is the same as it was when he was a little boy: he wants to win Grand Slams and he wants to be the best.”
