No I thoroughly understand those as players.
But I didn't understand signing Jesus and Sane whilst ignoring ridiculously obvious areas such as the full back positions. In Isolation both are great. I'd feel exactly the same about Bernardo this summer if we signed him but then ignored the goalkeeping position or the full back positions.
And in general I didn't understand Navas, Delph, Bony, Javi Garcia, Fernando, Mangala or Otamendi. I also didn't understand Bravo as a signing when we didn't bring in the required technically sound defensive players to operate alongside the type of footballing goalkeeper Bravo is.
