How are you gonna say Bernardo is past his best? The guy is in his peak years... He's 30 years old!Too many of our players are past their best, Walker, Bernardo, Gundo, KDB, Stones.
If we regain the title this year it will be Pep's finest hour.
Try and get to January and keep in contention, and splash the cash for a couple of inspirational signings.
Also, as for the rest of the names you mentioned.. you only have to look at far as Real Madrid and how well Modric and Kroos performed well into their mid 30s... Don't count those guys out they still have a lot to offer and they will this season you will see... Gundo is getting better every game, Bernando ran circles around their left back today... And KDB is still levels above anyone in the league.
Have some respect for the guys that gave their best years to the club and will still give their best in due time!
