Dont forget that Ovi's father died early last season. Whilst most people blamed Ovi's performance on Ole Father Time, I think it was more to do with him mourning his father. He wasnt himself at all last season.
His resurgence this season shows he's back to his old form, or dare I say it, even better. It's like he has something to prove.
My only concern is him maybe coming back too early, not fully recovered and nursing that injury for the rest of the season.
