Patrick Reed has courted controversy for his comments during and post Team USA's comprehensive defeat at the Ryder Cup over the weekend but now one source from his own team has claimed he is just "full of s**t". 

Reed had been critical of the decisions made by captain Jim Furyk and former playing partner Jordan Spieth and the anonymous source claims that this mindset cost the US team in the tournament.

Following their success two years ago the separation of Spieth and Reed raised eyebrows as Spieth was instead paired with friend Justin Thomas and Reed with Tiger Woods. Team USA were subsequently dominated by the underdog Europeans, losing 17.5 to 10.5.

Reed claims to have been 'blindsided' by the decision and told the New York Times that the decision-making process was “a buddy system” that ignored the input of all but a few select players while also pointing the finger at Spieth.

“The issue’s obviously with Jordan not wanting to play with me. I don’t have any issue with Jordan.

"When it comes right down to it, I don’t care if I like the person I’m paired with or if the person likes me as long as it works and it sets up the team for success.

"He and I know how to make each other better. We know how to get the job done. I thought [team captain Jim Furyk] might go back with the groups that have worked in the past.

“For somebody as successful in the Ryder Cup as I am, I don’t think it’s smart to sit me twice."

Now one anonymous source from within the US camp has told the New York Post that Reed's attitude derailed the rest of his team and ruined the chance of a US victory at Le Golf National.

“He is so full of s**t. Blindsided my ass. He begged to play with Tiger.

“He would have shot 83 on his own ball Saturday. He totally screwed Tiger. He has no clue how to play team golf.

"I saw firsthand how bad of a team player he was. Eleven players understood the concept of team golf and only one didn’t. Unfortunately, that one proved to be too costly for the team to overcome.

“I feel so bad for Jim, because he was an unreal captain. He would have run through a wall for all 12 of the guys. Unfortunately, there were only 11 players that would have returned the favour.’’
