DAZN host Kelly Somers was forced to apologise for John Obi Mikel's foul language after the Chelsea legend launched a scathing attack on Nicolas Jackson for the 'stupid' challenge which saw the Blues star sent off in the 3-1 defeat by Flamengo in the Club World Cup. <br /><br />Jackson's sending off topped six minutes of madness for Chelsea, who went from leading their Brazilian opponents 1-0 after 61 minutes to finding themselves 2-1 down - and with only 10 men - after 67 minutes.<br /><br />Jackson was dispossessed in the middle of the pitch and, in his over-eagerness to win the ball back, the Senegal forward stamped down on Ayrton Lucas. Referee Ivan Arcides Barton Cisneros had no option but to produce a red card.<br /><br />Just a month ago, Jackson's Premier League season ended prematurely when he was sent off for a similar challenge against Newcastle on May 11 and handed a three-match ban. <br /><br />And Obi Mikel, who was working as a pundit for DAZ, did not hold back when he was asked about the incident.<br /><br />'(It was) Unbelievable. Stupid, stupid, stupid mistake,' said Obi Mikel won two Premier League titles and the Champions League with Chelsea.<br /><br />'I don't know what was going through his head. You come into the game, and you are 2-1 down at that point. Your team needs you. And he does that. <br /><br />'He did it in a league game at Newcastle. Again, a crucial game which we needed to win to qualify for the Champions League. He did that, and he got a red card. And now he's done this. You can't keep making mistakes.'<br /><br />But it was when host Somers suggested that Jackson's frustration may have boiled over from frustration at losing his place to Liam Delap that Obi Mikel lost his cool. <br /><br />'I don't care what his frustration is,' Obi Mikel reacted angrily.<br /><br />'It's a football club. It's a massive football club, and it's about competition. If you're p***ed off that Delap's coming to the football club and he's going to be the competition with you...You have to embrace it if you are a big player. <br /><br />'Because the only way you are going to win trophies is if you are competing against each other.'<br /><br />It was at this point that Somers was forced to say sorry to viewers for her guest's language. <br /><br />'Lots of emotion in the studio, so apologies for any language used there,' she said, holding out both hands in a calming gesture towards Obi Mikel.<br /><br />After the match, Jackson took to social media to apologise for his actions. Writing on Instagram, he said: 'I want to say sorry. To the club, the staff, my teammates, and all the fans watching, I let you down. Another red card... and honestly, I'm so angry at myself.<br /><br />'Work hard every day to help the team not to put us in this kind of situation. I still don't fully understand how it happened. But one thing is clear: it wasn't intentional. Just a football moment that went the wrong way. No excuses. I take full responsibility.<br /><br />'I'll reflect, I'll grow, and I'll come back stronger for the badge and for everyone who believes in me. Sorry. Sorry.'
