Cleveland Browns general manager Ray Farmer has hailed young quarterback Johnny Manziel for his attitude in training.

The 22-year-old checked himself into rehab earlier this year to confront personal problems, but has been back with the squad in preparation for the new season.

Farmer told NFL Total Access: "Johnny's been good since he's been around the Browns family. I commend the young man for taking the necessary steps that he felt were needed to take.

"That being said, since he's been back here, he's been good. He's doing everything he's been asked to do. He seems dialled in and focused and that's what it's about, making football his first priority for us on this end, but, again, inevitably, we're really focused on making sure the young man has his life together."

Manziel played five times last season, but failed to throw a touchdown.
