Moses joined Chelsea back in 2012 from Wigan Athletic for £9m. He was loaned out by Jose Mourinho to Liverpool, Stoke and West Ham.
“I am more focused now than ever. I am enjoying my football again,” he said.
“We have got a new manager here who is willing to give everyone an opportunity,” said Moses. “He gave me that opportunity and I didn’t look back after that.
“I am very pleased with that and I just want to keep improving in every game I play. It is a new role for me and I am still getting used to it.”
