Am I right in saying that they have nobody in their squad who scored more than 5 league goals last season?
I would be very concerned about that going into a new season. They need a 20-30 goal a season striker just to be on a par with last season and regardless of who they sign, strikers tend not to immediately hit the ground running when moving to the Premier League. There tends to be some period of adjustment. What if Morata struggles to adjust like Morientes - the player he was compared to throughout the ranks at Madrid.
Yet their main targets so far have been a CB and a DM, two areas which were not a problem really. Personally think they should have signed a Ibra replacement and then another pacey striker as being reliant on just one FW as they were last season is very dangerous.
In contrast to us, who in Coutinho, Firmino, Mane, Lallana, Sturridge & Origi (and now Salah) have a group of players we expect to get 8-15 goals. Of course we have our own defensive problem to solve, but that seems easier (and cheaper) to fix than going into a season with almost no goal threat.
