Buffalo Bills head coach Doug Marrone has said that EJ Manuel must work on his footwork during the pre-season.

The Bills used their first-round draft pick to acquire the 23-year-old quarterback.

Marrone told the team's official website: "It's what I expected. Again, to work on the footwork and he made some nice throws. What I expected, I didn't think he'd come in here and be the polished guy that you have.

"You're learning a new system. You're learning new coaches. You're getting a feel for yourself. I try to look at the players and just say okay, here's where they are. Here's how they are on the field.

"I think as a coach, I know I've had this problem, if I create expectations in my mind of players that I've never coached before, I can find myself getting in trouble. So, I try to go in there open-minded until I get around them and get to know them."

Manuel is expected to compete with Kevin Kolb and Tavaris Jackson for a place in the starting lineup.
