Chelsea pair Nicolas Jackson and Noni Madueke are not the first team-mates to clash on a football pitch.

Cole Palmer’s four-goal haul in the Blues’ 6-0 win over Everton on Monday was overshadowed by what boss Mauricio Pochettino called an “unacceptable” altercation over who should take a second-half penalty.

Palmer, the club’s designated penalty-taker, finally took charge, following intervention from captain Conor Gallagher, recovering his composure to score his fourth.

Jackson and Madueke follow a long line of club colleagues to have had a very public difference of opinion. Here, the PA news agency takes a look at some previous incidents.

Lee Bowyer and Kieron Dyer

Perhaps the classic of the genre, the Newcastle team-mates came to blows towards the end of a 3-0 home defeat by Aston Villa in April 2005, Dyer grabbing Bowyer by the throat and the pair trading punches before being separated by Villa’s Gareth Barry. Both men were dismissed by referee Barry Knight – defender Steven Taylor had earlier been sent off for handball – and later hauled before the media by manager Graeme Souness to apologise for their conduct.

Graeme Le Saux and David Batty

Blackburn’s Le Saux was left with a painful reminder of his bust-up with David Batty during a 3-0 Champions League defeat at Spartak Moscow in November 1995. Four minutes into the game, the pair collided as both tried to retrieve a Mike Newell pass and Batty made his displeasure abundantly clear. The row descended into a pushing match before Le Saux – he later insisted in self-defence – struck out, breaking his left hand during a scuffle in which intervening skipper Tim Sherwood took a blow to the cheek.

Hugo Lloris and Son Heung-min

Tottenham keeper Lloris and striker Son became involved in a heated row on the pitch as the half-time whistle sounded in a 1-0 Premier League victory over Everton in July 2020. Lloris angrily confronted the South Korea international over his failure to track back and the pair had to be separated by team-mates Giovani Lo Celso and Harry Winks. The spat continued down the tunnel and into the dressing room, although the two men embraced after the final whistle.

Derek Hales and Mike Flanagan

Charlton strike partners Hales and Flanagan came to blows during an FA Cup tie against Maidstone in January 1979. The source of the spat was allegedly Flanagan reacting to Hales failing to pass to him by making a disparaging remark about his team-mate’s genitals. Both were sent off.

Craig Levein and Graeme Hogg

The Hearts duo became involved in a disagreement during a pre-season friendly at Raith in August 1994 after their side had almost conceded. Both men threw punches, but it was Levein’s which did the damage, breaking Hogg’s nose. He was sent off as he was being carried off on a stretcher with Levein suffering the same fate, and they were later handed 10 and 12-match bans respectively.
