Pro soccer player Kian Harratt was caught on video throwing a chair in the middle of a CRAZY poolside brawl, striking a woman ... though he insists she wasn't the intended target!
The melee went down last week in Ibiza, where the Oldham Athletic striker was having some fun in the sun.
But, the relaxing summer vibes quickly ended when Harratt and some guys got into it with another man who was poolside.
In the video, Harratt and the other men confront the other party ... while a woman tried her best to keep the peace.
