Just isn't true though, as has been debated so many times. What's revisionism is you stating that no-one has succeeded in coming up with a compelling argument for the neutral that the lad is effective. You don't like him, as is your right, therefore it makes debating redundant because nothing I or other pro-Bolasie players state will change your mind.
Bolasie has an excellent first touch and is extremely competent and keeping the ball. Before his injury and countless times for Palace also used his pace to get his team up the pitch, from his box to the opponent's.
If you want some stats to back up that Bolasie isn't terrible, he averaged 0.31 assists per game. Barkley averaged 0.22 assists last season with far more opportunity to improve that average given he played 36 games (Bolasie played 13). He also averaged winning a tackle a game. Barkley: 0.72. In the games played, Bolasie's assists totalled 4. Barkley 8. Again, Barkley played in 60% more of the PL games than Bolasie did.
Is he inconsistent with his crossing? of course he is.
Is he a bad player? of course he isn't. He's a good, effective player.
