I have every confidence Doku will take yesterday's game as a learning experience, as he comes across as a studious individual who is constantly seeking self-improvement in his game.
Mentally, seems quite the opposite to Palmer, who I was gutted to see leave the club but relies too much on his natural talent as commented within his interviews about pens. I reckon the club were privately frustrated in Palmer not doing the extra work or effort to step up to the next level with us & see a different mindset with Doku.
