It is unrealistic to sign 11 new players but you'd have thought he might be able to prioritise a bit better. Struggle how or why you'd want to cut him some slack when it's almost footballing suicide what he did in not getting a striker in. Let's not forget a majority of our business was done early so he had ample time you do something, anything, even a loan, but he completely screwed up. In my mind he shouldn't even be in a job at a multi million pound organisation with that level of failure.
Walsh? are you assuming he had free reign to sign any striker he rated with the attributes koeman required? My assumption is that he had a very short list of approved strikers from koeman rather than a free reign. Surely if that's the case then koeman is more responsible than Walsh is
