Lee Westwood questions Tiger Woods' role in US Ryder Cup team

Woods has not played competitive golf since the Wyndham championship in August 2015, and has been sidelined for much of the past year while recovering from multiple back surgeries.

The former world number one was recruited by US captain Davis Love III as a non-playing team tactician for next week's event, but Westwood, a wildcard pick for Europe, says he is not convinced Woods' presence will have the desired impact.

"I don't know what impact there will be from having Tiger around," Westwood said.

"They have always struggled to find a partner for Tiger that's been successful. He could have an adverse effect in the team room. People have always seemed to try to do too much when they have partnered him.

"It might be different if he's one of the vice-captains, you don't know."

Europe, fielding six rookies in Minnesota, will be gunning for an unprecedented fourth consecutive Ryder Cup victory next week.

"They have got a strong side and probably are favourites, but they haven't won it for a while and they are playing in front of a home crowd," Westwood added.

"There is a lot of pressure on them. That is going to keep building in the next week or so and by the time the Ryder Cup comes around, it is going to be pretty intense for them."

Love will announce his final wildcard pick on Sept. 25 and Westwood, making his 10th consecutive Ryder cup appearance, questioned the American captain's omission of one former major winner, saying:

"There seem to have been issues about team spirit and chemistry. Love has not picked Bubba Watson and I don't know what that does for team spirit; he was first outside the points qualification and is No. 7 in the world."

The Ryder Cup begins at the Hazeltine National Golf Club on September 30.
