Andy Murray, who skipped Roland Garros due to a nagging lower back injury, says that he is feeling much better and found it hard to watch the tournament from home.

"I think it can be easy to take things for granted sometimes," Murray told reporters at Queen's Club. "You know, I played pretty much every Slam for about seven years and I missed it. It was difficult watching and not being there. You realize how much you love competing and you love being around the tournaments. When everything is good and you're healthy and you're playing every week you don't often think about it that much. And when you're away from it and you miss one of the biggest tournaments, one of the tournaments you prepare extremely hard for and put the hard work in for, then it's tough.”

Murray, who reached the 2012 Wimbledon final and won the Olympic gold medal at the All England Club last season, says that his confidence level on grass has risen.

"I probably feel a bit more confident coming into this grass court season because of how I played on it last year," he said. "I think because I managed to win some big matches and play well on the grass last year, I know what I did well and what I need to keep doing."
