He did do it for Palace the season before we bought him and he hasn't done it since because the knee injury ended his time as a decent player which I've been saying since the start.
But this is just silly. How many players hit every cross where they want it to go? I'd say Digne is good at it, but I've seen shockers from him. Part of being an attacking player is failing because you're trying to do something that is extremely difficult.
Now to be fair, if your problem is with the style that Koeman was trying to use with him in the team, I agree. But that isn't a criticism of Bolasie.
And for the very very rarely effective part, well it certainly wasn't good enough, but which of our creative players since then have been more effective? The answer sadly is no one. Which is why I can't understand his abuse going above and beyond what others seem to get.
