Where does this lost possession stat come from? I have seen it quoted on planetfootball but no source for it no details on what it really means. For example Lukaku is clearly involved in a lot more aerial duels last year, if he wins the majority of them, but has no player around him then do those count as possession lost. Ibra is difficult to compare against, largely as he stands out compared to most strikers for his possession stats, when you look at Squawka for their possession stats, he is reasonably comparable to most players.
Genuinely I don't think people would like anyone unless they were named Morata. Its unclear whether we wanted Lukaku and/or Morata, but its clear that Morata was unavailable for whatever reason, this idea that Morata was available at a lower price hasn't been confirmed has it, as far as I know the figures quoted were all based on guesses. Maybe Madrid wanted De Gea plus 60m for him, who really knows.
