(20-08-2010) Chelsea midfielder Jon Obi Mikel is determined to fight off the challenge from the club’s new signing Ramires.The Blues signed the Brazilian midfielder from Benfica for £18m last week. But Nigerian international Mikel claims he will fight tooth-and-nail to hang to his place in Carlo Ancelotti’s side. "I'm very happy playing under Carlo Ancelotti. After a season together I feel I know him well,” said Mikel on Thursday. "He's a manager I can speak to, in many ways he's like a father. He gives me great confidence."
