Real Madrid knows that Barcelona are out for tittle this season,and will definitely do anything to win the Lalliga trophy.Xavi and his men are aware that Real Madrid is the only major threat they have,so they will want to do everything possible to win most of their games so that the league table will favour them.I see Barca winning the Lalliga this season.
Real Madrid needs Barcelona to maintain the television rights deal at high price. They need to co-exist and grow together for mutual benefit. Even Barcelona is taking high risk in this summer with lot of risky deals, Real Madrid does not want to see Barcelona collapses and goes to bankruptcy.
About La Liga title competition, I think Barcelona gives their fans some hope from this transfer season but as said, lot of risk from it and Real Madrid is still in better conditions.
But Chelsea's interest in Aubameyang doesn't seem to get a good response, because Aubameyang still wants to stay at Camp Nou. This 33-year-old player does not want to leave Barcelona immediately, because Barcelona is still a comfortable place for him. Aubameyang's contribution to the Champions League has been quite a lot by creating 13 goals in 23 appearances in all competitions last season.
Aubameyang likely found his second career in Barcelona. After a big drama and drag down in last months in Arsenal, he came back to his best performance in Barcelona.
Old players have more space to play in La Liga than in Premier League. They don't have to join with physical fighting seriously like in Premier League. Personally Aubameyang likely prefer to play in La Liga than in Premier League.
Aubameyang's contact is still less than 3 years until June 2025
With Barcelona's chaos and fastly changed plan, I don't believe Aubameyang will complete this contract.
