Jose Maria Olazabal says he will not be influenced by a previous falling out with Padraig Harrington when he picks his Ryder Cup wildcards on Monday.
Olazabal fell out with Harrington at the 2003 Seve Trophy in Spain over the repairing of marks on a green before the Spaniard putted.
But Olazabal has denied suggestions the problem will affect his judgment.
"There is not a single bit of truth in that," he told BBC Sport. "If that was the case I'd be failing as a captain."
Harrington cannot qualify for one of the 10 automatic places in Europe's team, but may be a contender for a wildcard - although England's Ian Poulter seems sure to be one of two picks for next month's match at Medinah.
Olazabal raised eyebrows by saying the Dubliner needed "at least a win" at the Barclays Tournament in Farmingdale, New York, this weekend to make the Ryder Cup team.
"I am just looking at players, what they have done, how they have played and I want to get the best players for that team - whoever they might be," Olazabal added.
Harrington opened with a 64 at Bethpage Black but followed it with a 75 to dent his chances. Belgium's Nicolas Colsaerts is another leading contender for a one of the two wildcard picks to be announced at 12:00 BST on Monday.
Colsaerts can also overhaul Germany's Martin Kaymer for the final automatic qualifying spot with a top-two finish in the Johnnie Walker Championship at Gleneagles.
