I still hold the opinion that Keïta is the most complete midfielder in the Premier League. Insane dribbler, passing is excellent, can score goals. And what sets him apart from others is that he has the defensive contribution to back it up. He's a demon waiting to be unleashed.
Disclaimer: Don't confuse "most complete" with "best". I'm not saying he's the best midfielder in the league, nor am I saying he's necessarily the best in any of these particular attributes. Just saying as an all rounder there's no one like him.
