I shake my head when I see takes like this. How do you follow Pep's Manchester City and say he was successful only because he has financial backing? Do you know how that sounds?
Klopp has spent almost as much as Pep in Liverpool. Klopp has a net spend of about £900 million. Check how much Arterta has spent so far in Arsenal. What about Manchester United which has a net spend of over £1.2 billion post Alex Ferguson era?
Most recently we have Chelsea that have spent a billion on transfers in the last two seasons, yet all these clubs don't have Alf the success of Manchester City in the Pep era. So how do you say he's successful because the club grants him all the players he needs?

I know that you can't be successful without good players, but at the end of the day, it comes down to the wit of the manager. Pochettino has Messi, Neymar, and Mbappe in his team and struggled to win even the Ligue 1.
My point is, no matter how much a club spends on transfer, if they don't have the right manager they won't be successful.
Funny enough the players Manchester City but are not so expensive. Now they've gotten Savio from Girona if he comes to the team and turns into a beast, people will start talking about how Manchester City always signs good players. No manager in the top 6 would do what Pep is doing to Doku.
Give Pep his flowers, he's successful because he's good.
