Lets play a fun game of These Managers Aren't Good Enough For Us! I'll give you 3 options which I'm sure will be much more tempting than Silva:
Manager 1: He managed 4 clubs in Argentina, never lasted longer than a year at any and left the last two due to poor results, then spent just 6 months at a relegation fighting club in Spain, then just 6 months back at an Argentine club - what a terrible record! He must be awful! Kept on leaving clubs!
Manager 2: got relegated with Nancy, got sacked by Monaco when they were 17th, and spent 3 years managing in Japan... He sounds like a bit of a loser doesn't he! Only managed in poor leagues!
Manager 3: spent one year each at 4 Italian clubs, got one relegated, left the second because he was tempted by a bigger club, left the third when the were 19th in the league, and spent the 4th year in Serie B.... He sounds a bit rubbish too doesn't he, not to mention disloyal!
Well those are the careers of Diego Simeone, Arsene Wenger and Antonio Conte at the point when they joined Atleti, Arse and Juve respectively. I've picked them as they're relevant now but there are LOADS of similar examples.
I'm just a bit bored by people who instantly dismiss Silva because they see some defeats at Hull and Watford and think he can't be good enough for us. Looking at club names and results without ever actually watching the football. Of course he's a gamble but I'm happy to take a chance on someone with a growing reputation for good attacking football and great man management skills and see how it goes... It's going to be more fun than Sam's hoofball anyway.
