Yes, after leaving.
It was posted on here the other day but David Raya's recent interview says it all:
David said. "If you watch highlights from me when I was back at Blackburn, you will see a keeper that just stood on the line, not coming for anything, rarely going for a cross, rarely going outside the box, rarely anticipating, just waiting to make that save.
"When I signed for Brentford, Inaki just completely changed my style of being a goalkeeper, to be more proactive and anticipate stuff that has not happened yet. So, if you can go for a cross, just go for it. Don't wait for the save. Instead, avoid the chance. For balls in behind and all that, stay high as much as possible to be able to cut out the attack.
"If you see me at Blackburn and then after I signed for Brentford, it's two completely different goalkeepers. At Blackburn, I wasn't going for any crosses. And then at Brentford and here, I think my numbers on crosses are remarkable.
Brentford were in the same league as us yet they had a goalkeeping coach that was miles ahead of ours. Why wasn't he being taught those things at Rovers?
