Can this potential Barcelona side challenge for the CL/LL?

[Temptation]

Apparently, Xavi wants Bernardo Silva and a FDJ move and some other outgoings might get him in.
. Let's assume Silva deal is somehow completed.

Other realistic incomings would be Christensen, Kessie, Azpilicueta, Alonso and Lewandowski.

This is what the starting 11 would look like:

MATS
Azpi Araujo Christensen Alba/Alonso
Gavi Busquets/Kessie Pedri
Bernardo RL9 Fati/Ferran

I think Bernardo Silva would be an excellent signing since he's so good in possession, a great ball carrier and works hard off the ball despite being an attack/possession oriented Footballer.

While this team is far from perfect, it does have a nice mix of experience and youth.

Some of these incomings will also add leadership skills and winning mentality.

Personally, I believe this team would win La Liga.

But realistically, can you see this team challenging for League/CL(any of the 2) and why/why not?

No chance. As long as Busi is still playing 99% of minutes, the first big team in the CL will humiliate us again. Add to that a GK where every shot is unsaveable, a LB who will start crying as soon as we concede. Those mentioned transfers won't help one bit, Bernardo is to slow as a RW, Azpi is to defensive and slow, Alonso is shit at defending while also being slow, Christensen is the Danish Lenglet, Kessie is no DM, and Lewa won't score half the goals he scores for Bayern, because we won't create half the chances they do.
