Wellington Phoenix striker Paul Ifill has accused Adelaide United Fans of racially abusing him during his side's 3-1 loss in the Australian A-League on Sunday.

The British-born former Barbados international tweeted his displeasure after the match, saying he was subjected to racial abuse from a small number of fans.

"Bad times poor result and racist abuse from a minority of fans," he wrote, adding in a follow-up tweet: "no problem with a bit of banter but a line was crossed today."

The 33-year-old, who has been with the New Zealand-based Phoenix since 2009, said it was the first time he had experienced such treatment in the A-League.

Wellington's Dominion Post newspaper said police and Adelaide club officials were informed of the abuse allegations and Football Federation Australia was investigating.
