His pace seems to have gone. There was a few times last season when he got the ball on the break and, in the old days, that meant he was away and in on the keeper. He's still decently pacey but that rocket fuel has been replaced by unleaded.
Maybe a mixture of that and loss of confidence?
Or maybe playing him out on the left doesn’t suit him at this stage of his career?
Hopefully Frank can get him playing again as he used to
