Looking for..

Hey I'm looking for a manga with a baseball or soccer theme, it's about a teacher who recently transfers to the school after he gets fired from his old one for hitting another teacher. He's very hotblooded but a great guy and all his old pupils love him and his new pupils just see him as a moron, but he tries really hard. The new pupils are delinquents and slowly come around and then they love him too. Thanks for your help. <3
