Sammy Watkins has admitted that he still has work to do on his partnership with EJ Manuel at the Buffalo Bills.

The team picked Watkins in the first round of this year's Draft to provide their quarterback with a new weapon.

However, the wide receiver told NFL Total Access: "It's not fully there. I mean, we've been connecting at mini-camp, and OTAs. But at the same time, I could be wide open, and if he don't feel it, or if I run it a different type of way, he won't throw the ball.

"So it really just got to come with him believing in me. I believe in him. He can throw just about any ball. So it just comes down to, we just need a lot of reps."

Manuel completed 1,972 passing yards in his rookie season with the Bills, but missed six games with a knee injury.
