Former World No. 1 Luke Donald believes the European Tour has to concerned at the ever-increasing European-born talent drain to the rival PGA Tour.

All but three of last month’s victorious European Team in Scotland’s Paul Lawrie, Italy’s Francesco Molinari and Germany’s Martin Kaymer will play full time in 2013 in the States.

Lee Westwood’s now bought himself a house in the States and Belgium-born rookie Nicolas Colsaerts has earned enough money this year in the Majors and WGCs that he’s making the move.

And set to join him is PGA Championship runner-up, England’s David Lynn while Ireland’s Shane Lowry, who is fourth heading to the weekend rounds of the $7m WGC – HSBC Champions event in Shenzhen, China, is planning to play more across ‘The Pond’.

A host of other Europeans, including former Ryder Cup star Ross Fisher, and Tour winners Simon Khan, Jamie Donaldson, Maarten Lafeber, Robert Jan Derksen and Alex Noren plus Rafe Echenrique and Oliver Fisher will contest next fortnight’s PGA Tour Second Stage.

Donald said:  “If I was the European Tour I probably would be a bit worried with a lot of suggesting they are going to play their minimum in Europe but concentrate on the U.S.

”If they don’t at least try it for a year or two, they’re going to have regrets.

“There are some great events in the States, and geographically-wise it’s easier to travel.

“You’re not travelling country to country, the tournaments are a lot closer together, you’re playing for pretty good prize money and you’re playing against the best competition. It’s a very attractive tour.

“The European Tour is still strong and we’ve proven that in the Ryder Cup.

“But as long as we keep being competitive in that event that’s what counts.

“I’m sure the European Tour is watchful about these guys leaving but there’s not much they can do.”
