Baines was/is a good crosser. He did pick his head up, more often than not, during the 3-4 years when he was in his prime and had Pienaar there.
I get what
@davek is saying in that he does also tend to just lump it in, and since Pienaar declined/went, that was an issue. With Pienaar, Baines had the time and space to drive forward without the ball, meaning he could see the picture in his head by the time he got the ball back (basically he'd already done his looking, so it was less hit and hope and more having that image already there).
Digne is definitely more of a 'passer' with his crosses. They seem to be aimed at a direct point every time, which is great to see. Hopefully it continues because overall he's made a brilliant start.
