What do people expect? If the forum had it's way Frenkie would probably be our oldest player
Rebuild doesn't mean we have to kick out every veteran (applies to Busquets as well, who can still add a lot). In Roberto's case it's mainly the issue of salary for me. He should be on 80-100K/week at best. And that's generous.
You need balance in the squad without doubt, going full youth will make us the new Arsenal for sure.
But we also need to be selective, for example I liked Aguero signing, didn't care much that he is 33 as long as he can provide a help from the bench 50% of games.
Now with his heart condition, it is awful signing because he isn't helping.
Regarding Busquets and Robert:
-Roberto became more injury prone and lost a good portion of his quickness, he was very quick for a midfielder and average one for fullback, that was 4 or 5 years ago.
Seeing what happened with the likes of Umtiti and MATS, with an older player like Roberto I wonder if it is smart decision to keep him.
But as you said, salary is big issue because at the end of the day Roberto is a versatile bench player who gets his minutes when other players are injured/suspended, so him on reasonable salary and number of years won't bite us in the ass later. At worst it will be meh kind of deal that every club including successful one has done before.
-As for Busquets, I think the issue is deeper
I mean help me here, tell me a player in this club who was 34 (Busquets age next season) at start of a season that was starter through that season? I have been a fan of the club for over 20 years and I am not sure I remember correctly
Messi, Xavi, Puyol, Alves, Iniesta didn't make it as starter till that age.
Only 2 I remember? Thuram in 06/07 and that was due to Marquez injury at the end of the season iirc (wasn't starter in CL) and Pique in current season is in his way to end it starting most games.
In both cases, the players really weren't Barca level starter.
Busquets has been a liability for few years now, and it is going one way, initially it was his defense in counters, then his overall defense and now it is his on the ball skills. He is now being targeted by opponents.
Then again, can Busquets be helpful? sure, as bench player who is well rested I think he can.
But is he getting that bench type of treatment? I doubt it, team captain who is coached by a guy who is his biggest fan.
It is just we can't afford Busquets as starter for another year, and he probably wants playing time for the World Cup. we just need to move on from him.
We can't keep Alba (33), Busquets (34), Roberto (30), Pique (35) as squad players next season. not even 2 of those should stay and Alba is going to stay.
At least one needs to leave.
What we need is more players aged 25-28 in the mercato, we have enough youth and overload of old players.
PS: I am speaking about next season because we already have the squad set for this year, no one is coming to take minutes from those two in the winter
