A potential split of the Rory McIlroy-Graeme McDowell partnership in the Ryder Cup is more about their record than their lawsuit.

Both players have made it clear that a lawsuit involving an Irish-based management firm is not an issue at Gleneagles. European captain Paul McGinley is more concerned about their record.

McGinley says the Northern Irish duo has won only two out of the six matches they have played.

He says if he doesn't put them out together against the Americans, it would not stem from any issues off the course. McIlroy is suing Horizon Sports in a lawsuit that involves McDowell.

It was a festive start to the week at Gleneagles. The Americans arrived Monday morning, with Rickie Fowler sporting a haircut with USA on the side of his head.
