The 24-year-old returned to first-team duties for the 2-1 win away to West Ham United on Sunday, having being absent since December 29 through injury.
He told the club's official website: "I was very happy at West Ham as I'd worked very hard to get back to full fitness. So that's been achieved now.
"I was simply just making myself available for the team, because the most important thing here is the group, so you need to be ready to give your absolute best when you are called upon."
Kickoff for tomorrow is scheduled for 1.37pm.
