For so long we'e failed to add to/replace the core of 2012 with players of that calibre and consistency.
Hart, Kompany, Toure, Silva, Aguero.
It isn't for want of trying but very few signings have stepped up to that level. They've either failed or been fringe or decoration players. Fernandinho is probably the only one who I'd put in that category and he signed in 2013!.
Does anyone believe Bravo, Stones, Gundogan, De Bruyne, Jesus are the answers? I hope so and some have big futures with us but it's taken 5 years.
In the meantime the rest of the team has undoubtedly gone backwards. The full backs are old. We've never successfully replaced Barry and De Jong (Rodwell, Garcia, Fernando, Delph). Dzeko hasn't been replaced. Okay Negredo briefly did a job but other than the failure of Bony have we even tried to replace him? We've got through loads of centre backs trying to either find a partner for Kompany or a replacement. One area you can argue we have improved is in 2012 Johnson was our only winger and Sane and Sterling are superior with Navas as the other option.
I might get shot down for this but frankly we've wasted a lot of time and money and not improved the team in 5 years.
