Vernon took to Twitter to express his disappointment in the field, saying: “nother stellar field against Mo Farah on home turf this weekend at Birmingham. #joke,”
Incensed, Farah responded, sarcastically pointing out that Vernon would not be lining up alongside him.
Neither athlete seemed willing to let his rival have the last word, and with more than an hour gone, Vernon tweeted: “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.”
He said: “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!”
