Enough time for what? We're in a league where anyone can beat anyone on any given day. What exactly are you expecting him to be able to do between now and the end of the season that will suddenly make us the dominant force over sides that are more or less our equals on paper? If you think we can do it, what stops the other 23 teams from making that improvement too and maintaining their positions? By and large, our resources are fixed for the rest of the season, and it would be pot luck if we managed to bring in a few signings or find some gems in our youth team that can significantly improve the team overnight.
We were one result away from finishing 9th last season, are the lines of success and failure so clear cut that one game out of 46 can decide whether someone keeps their job or not? Targets should be set over seasons, not games.
