Mo Farah has been accused of swearing at Andy Vernon following his win in the 5000m in Lausanne.
However, Vernon has claimed that when he went to congratulate his British teammate on his win, Farah verbally abused him and spurned his offer of a handshake.
Vernon told reporters: "I went to shake his hand and he turned his back on me and told me to fuck off. I wanted to bury the hatchet, I'm going up to Font Romeu [where both men train] in a few days' time and I just wanted to end it.
"To not even be a sportsman there and shake my hand I think is pretty disgraceful, to be honest. Like in the armed forces, you salute the rank, not the person sometimes. I wanted to congratulate the performance. Whether we're friends or not, I can appreciate a good performance but I get that reaction.
"With all the bad publicity he's getting at the moment I would have thought he would try to actually make a good name for himself again but by doing that it's not too good for him."
The duo were involved in a spat on Twitter earlier this year.
