Farah Lays Into Vernon In Twitter Rant

Mo Farah has labelled 5,000 and 10,000m rival Andy Vernon an "embarrassment" in an astonishing Twitter exchange between the British duo.

Farah took to social media to vent his anger after Vernon criticised the lack of high-level competition the 31-year-old will face on his seasonal debut at the Sainsbury's Indoor Grand Prix on Saturday.

"Another stellar field against Mo Farah on home turf this weekend at Birmingham. #joke," wrote Vernon.

Farah replied: "Shame you didn't make the line up....again #ComeBackWhenYouWinSomethingDecent"

Vernon, 29, responded: "Lol Mo Farah I think even you can work out that I can make the cut to the Indoor Grand Prix. Lets hope no one loses their shoe..."

The argument continued as Farah responded: "I wish you did make the cut mate so I can leave you in my dust like ALWAYS!! hahahaha #hatersgonnahate"

The exchange continued for an hour, with Vernon replying: "1) stop quoting Taylor Swift. 2) I don't hate you Mo. I would just rather watch a race than the the Mo Show. #playersgonnaplay."

At that point, Farah made his most stinging remark as he tweeted: "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!"

Farah will be the star attraction at this weekend's meeting at the NIA Barclaycard Arena in Birmingham which also features European 100m champion James Dasaolu and European and Commonwealth 200m silver medallist Jodie Williams.
