Arsenal manager Mikel Arteta says he decided to make a barbecue rather than watch the match that clinched his team the Premier League title.Arteta was due to watch the Bournemouth-Manchester City game with Arsenal's players and coaching staff at the club's London Colney training base on Tuesday evening, but he left before kick-off because "I couldn't bring the energy that I wanted".Instead, he went home and started to grill in his yard, only "hearing some noises in the background" as second-placed City could only draw 1-1 to leave Arsenal as English champion for the first time since 2004."My oldest son opened the garden door," Arteta said, describing the moment he discovered Arsenal had won the title "He started to run towards me, he started to cry, he gave me a hug and said, 'We are champions, daddy.'"And then my other two boys and my wife came over and it was beautiful, just to see that joy on them as well … it was magical."Thousands of supporters — and some of the team's players — celebrated outside Arsenal Stadium deep into the night, and Arteta was struck by how much it meant to a fan base that had lived through runner-up finishes in the league in each of the past three seasons.Arteta described it as an "emotional explosion"."Everybody's been just keeping emotions and living those emotions, but not being able to really express them," he said on Thursday
