I think you're unsurprisingly (given its you) being a bit hard on him here. Yes he wouldn't be my choice but you can't argue with 3 wins in a row and especially the way they demolished a team away from home in 20 minutes yesterday. That was impressive and as for "it's only Charlton"......you do know Arsenal. Man City and Chelsea aren't in this league right ?
It was "only" Blackburn, Hull, Pompey, Preston earlier in the season but yesterday was a million miles from the horlicks those games were.
If they get results in the next two matches he will get the job. They've been itching to give it to him anyway. I just hope these players who are currently playing for him remember to carry on doing so when he becomes their full time boss !!
