Former Chelsea captain John Terry was keen to remind Piers Morgan that Arsenal have gone nearly two decades without a Premier League title - before being told he will never be 'Invincible'.
The pair traded blows on social media, which began with Morgan revelling in Arsenal's league position. The Gunners have enjoyed a sensational first-half of the campaign, establishing a five-point lead at the top of the Premier League table, with a game in hand on some of their rivals.
Chelsea meanwhile have endured contrasting results, languishing in mid-table having changed their manager following the arrival of new owners. Todd Boehly has been keen to push the club's new-found American wealth following last year's takeover, spending over £500m since arriving in west London, albeit without the results to show for their largesse on the pitch.
