we already have unbalance team.
other than Aguero, which player scores regularly for this team?
no one.
i will consider them regular goal scorer if they can scores 20 goals per season, consistently.
in between 2 title winning seasons,
we once have Aguero, Tevez, Balotelli, Dzeko, Negredo and Yaya,
which scores more than 15 goals per season.
and for the last 2 seasons, only Aguero left in that list.
(and KDB with 16 goals, but he's more effective as goal provider)
we desperately need another top goal scorer.
Gabriel, Nacho and Sane, they are prospect players,
rather than proven goal scorer in top league.
there are an extra cup competition in this league.
Pep can always play them all and rotate the squad to stay fresh.
ship out yaya, nasri, hart, mangala, zuculini, navas, bony, clichy, zaba, sagna, etc
buy Sanchez, back up GK, young DM, senior CB and both fullbacks.
-------------------------- Sanchez/Gabriel ------- Aguero/Nacho
--------------- Sane/Nolito ------------- KDB/Silva --------- Sterling/Roberts
--------------------------------------- Dinho/young DM
--------------------- (usual back 4 with inverted fullback,
wide position already covered with 2 strikers and wingers,
no need to storm up front frequently)
Alexis Sanchez has never scored 20 goals in a season, so he doesn't even fit your own benchmark.
