Rangers have been linked with a move for Michael O’Halloran in the January transfer window.
Wright was angered upon hearing of the SPFL seemingly jumping the gun over a potential deal, and said that such incidents would never be allowed to happen to the so-called bigger clubs.
"But it's okay to do it for a small club, it wouldn't happen to any of the bigger clubs. They wouldn't dare do that to any of the bigger clubs.”
Wright’s frustrations are clear for all to see as his club fight tooth and nail to hold on to their star player amid interest from Rangers.
The Gers have already seen two bids rejected for the striker, as reported by Sky Sports, and a third bid is expected to take place ahead of Monday’s transfer window deadline.
O’Halloran has been with St Johnstone since 2014, recovering from a disappointing spell south of the border where he struggled to make an impression at Tranmere Rovers and Carlisle United.
A recent report in the Daily Mail claimed that the 25-year-old had already agreed terms to join Rangers, although a fee between the two clubs has yet to have been agreed despite ongoing talks.
Boss Mark Warburton is keen to strengthen his ranks this month, with O’Halloran now topping his list.
