Former world number one Martin Kaymer has not given up hope of making Padraig Harrington's Ryder Cup team for this year's tournament, despite conceding his game is currently not good enough for the PGA Tour.

Kaymer famously secured the point which ensured Europe would retain the Ryder Cup following the 'Miracle at Medinah' in 2012 and won his second major title at the US Open in 2014.

The 36-year-old has not tasted victory since his wire-to-wire success at Pinehurst, blowing a 10-shot lead in the final round in Abu Dhabi in January 2015 and almost dropping out of the world's top 200 before enjoying an improvement in form with six top-10 finishes last season.

However, after carding rounds of 77 and 76 to miss the cut in the Honda Classic in March, Kaymer has turned his attention to the European Tour and will battle freezing conditions in this week's Austrian Golf Open.

"I noticed when I played in Florida a couple of weeks ago that, right now, my game is not ready for the PGA Tour," Kaymer said. "My game is ready for the European Tour and I feel I can win on the European Tour and that is something I'm focusing on for the next few months.

"Playing those events where you have been successful, where you feel at home, where you feel comfortable, that's why I also chose Austria. I know it's a place where I feel like standing on the tee tomorrow morning that I can win the event.

"It's very important just knowing and believing you can win this week."

Kaymer is currently a lowly 47th in the Ryder Cup standings, but with points doubling from mid-May until the end of qualifying in September, he feels he can still book his place in the side or earn a wild card from captain Harrington.

"It's always there, that belief, and I think I need a hot summer, a couple of wins maybe," Kaymer added.

"If my form is really good three or four weeks before the Ryder Cup maybe it's enough, or maybe Harrington might want me on the team. Who knows?

"But I will never give up on that goal because we all know that form is very important when you get into the Ryder Cup. You don't always need to play great golf in advance in order to make the team. If you are a hot player two or three months before I think you might have a chance to be on the team."
