Mo Farah has labelled British teammate Andy Vernon an "embarrassment" during a lengthy Twitter spat between the pair this evening.
Vernon had initially criticised the lack of competition to face his fellow 5,000m and 10,000m runner at next weekend's Indoor Grand Prix in Birmingham, saying: "Another stellar field against Mo Farah on home turf this weekend at Birmingham #joke."
Double Olympic gold medallist Farah hit back at these comments by suggesting that it was a "shame" Vernon had failed to make the cut for the event, before later adding: "You're an embarrassment!! Taylor swift can probably run faster than you!"
@AndyVernonGB that's why they didn't put you in the race mate.. Cos you're an embarrassment!! Taylor swift can probably run faster than you!
