RORY McIlroy's plans to become the €191m face of sportswear giant Nike could turn into a bitter legal battle.
US sunglasses maker Oakley has launched proceedings to retain sponsorship of the world number one golfer.
The 23-year-old champion is set to rubberstamp a 10-year deal with Nike. He is expected to be announced as the new face of the sportswear giant Nike on Monday.
"Oakley's contract with Rory has a right of first refusal that permits us to retain Rory as an Oakley endorser by matching any offer he receives covering our products," said Oakley.
The golfer started off the New Year, before travelling to Abu Dhabi, by enjoying a break in Australia with girlfriend Danish tennis player Caroline Wozniacki.
The pair seemed to be in good spirits as they enjoyed the Sydney Tower Skywalk. They were even forced to deny engagement rumours after Wozniacki was spotted with a diamond-studded ring on her left hand.
Caroline (22) wore a large sapphire and diamond ring on her left hand.
