If anything I'd say you're overcomplicating the game for no reason. We've played the same slow and ponderous style for the last 18 months/2 years and it's not worked, so why on earth would you continue doing the same thing game after game? Leicester and Tottenham are both currently proving there's no one style of play that's guaranteed to be successful, you don't have to try and emulate Barcelona to win games, you need all XI players playing together as a team to be greater than the sum of the individual parts.
All this bollocks about "needing a central midfielder who can dictate a game, pick a pass, penetrate the oppositions midfield, find our attacking player's feet with sharp, incisive passing" - when was the last time Yaya did that in big games consistently? You might get odd world class performances which paper over the cracks. Consistency wins you league titles, not 4 or 5 performances a season. Again look at Leicester and Spurs, who do they have that plays that role - absolutely fucking no one.
I'm not saying I want us to play like Leicester, defending like fuck and hoofing it up to Aguero, not at all but if things aren't going well then you go back to basics and they're the team that do the basics better than anyone. You defend compactly, work hard, close down quickly and do the dirty work - then the quality will shine through in the short term. Spurs are doing it the right way, they're not anywhere near as good as us technically but they're probably the closest in terms of style of play and work rate.
