Which has always been my point. If we're swimming in the same pool as your Sean Dyche's then other candidates such as Allardyce and Pulis fit that bill better, are proven, and more experienced.
As for Silva...to me he's a 'meh'. He could end up being outstanding, could be no better than what the above managers could produce.
But overall, it's incredibly small time with zero ambition.
Dyche is certainly a safer option but Silva looks the better to me.
We aren't going to attract a ready made top quality manager right now such as Guardiola, Mourinho or Simeone despite Moshiri's dreaming.
Silva does seem to go into a club and have a virtually immediate positive impact, he seems to have the ability to take a pack of badly performing players throw them in the air and produce a team that maximises what potential it has, even if that is very little.
If we can't get the ready made choices then the next best realistic choices are those who may become top managers of the future but have yet to establish themselves.
Sometimes you can see as with Rodgers at Swansea or Martinez at Wigan, that despite sometimes indifferent or even very poor results there may be something about their approach to football that could pay out big time at a better club.
With Roberto unfortunately we found the faults inherent in his methods were just too large and the risk we took ultimately failed badly. This need not always be the case and Pochettino was very much small time and unproven when Southampton took him as are all the good and even better than good in their early career.
Its more to do with whether you think the mans methods have the potential to pay off with a larger club and more money, its obviously a risk but then so would Dyche be (and I agree it would be a far safer choice right now but although more pragmatic it would also possibly be more small time too).
I'm not against Sean Dyche at all and realise he's really restricted both to expenditure and possibilities in varying his methods at Burnley. The long ball works there and he's getting results.
I don't though however think opting for the perhaps riskier although imo far more ambitious choice is small time whatsoever.
The long ball stigma unfortunately once acquired by a manager normally sticks, however unfair that is in some cases, and I think unfortunately Sean Dyche has been tarred with that brush and will find it difficult to get a better job than Burnley despite what he achieves there, and there normally is a ceiling as to what is possible too - (Leicester the great miracle is unlikely to happen again in our lifetimes)
