I think you can. Football is about players, not money. Money is just something to get you players and Chelsea spending big money on Drogba and Shevchenko has no bearing on their success today (apart from it making them a bigger club but we can already compete with that). We could’ve fought for Costa, Willian, Kante if we’d wanted them.
It’s not like we have a League One squad + Sanchez + Ozil and we’ve got to spend 35m each on 9 positions to be able to compete with Chelsea. I think at the start of the season many thought our squad was quite close to Chelsea’s. I doubt anyone would have said they were 19 points better than us.
