I think only a small minority have dismissed him completely after 7 months in charge. That's not to say they're inkling is wrong, many others who haven't dismissed him yet are probably sick of the chopping and changing.
'as a manager he has the ability to make it to the top'. I have to point out that's just an opinion - not fact.
'Since Jan he has added some good players'. Well, just one - Sturridge and he's been on our radar for a while. Coutinho is only a prospect.
'we play some great football'. Arsenal have been playing great football for years under Wenger but have won nothing for the last 9.
The level of respect you're suggesting has to be earned over time. I agree it's too early to write him off completely but he's walking a tight rope in my opinion. I haven't seen anything outstanding in terms of psychology, motivation, tactics etc. so far.
I'll give you a few examples from last where he missed a trick:
- he said that he was here for the 2005 CL Semi against Chelsea and believes that the Garcia goal didn't cross the line. If he was clever he would've said something like... 'well, I didn't think it was a goal at the time but I now realise the truth'... i.e. tongue in cheek maybe but it has an effect.
- he used the above mentioned example to suggest that it was the fans reaction that night that led to the referees decision and then went on to plea for similar support on Thursday night for a similar effect. Well, such an overt request for pressure on the ref is embarassing in itself, but surely to make it open in advance is only going to make the ref think 'I'll be careful not to fall for that'. Could it have prevented the ref from giving a pen for hand ball?
- then of course there was the double sub at the point of going 3-1.
Not completely given up just yet, but far from convinced. His credentials are based on perceived potential as opposed to proven quality at this level.
