Not at all. It's been a perfectly decent window.
I think we've accepted our position as a consistent Europa qualifier. There's no chance of competing with the 5 powerful club. Just look at who they are signing and what they cost. We're better off consolidating our position as 5-7 in the league and pushing for the new stadium.
Our own Chairman has shown that he isn't satisfied with that (hence the repeated managerial firings). That's really the big problem here. We don't want to engage in any net spending, but the club's brass expect top results. When said manager fails to achieve the unrealistic expectations, he's shown the door.
