Arsenal’s record signing was closely examined by Manchester United before they passed on a move, reports the Manchester Evening News.
Romelu Lukaku had the attributes the Red Devils’ manager wanted, with the ultimate proof being Monday’s unveiling after a five-year contract was signed and a £75m-plus add-ons fee agreed with Everton.
While Lukaku trained for the first time with his new team-mates on Monday in Los Angeles, Lacazette has since landed in Australia after a record £46.5m arrival from Lyon.
It’s understood the French international was ruled out as a United target after Mourinho received scathing scouting reports.
While Lukaku scored 26 goals for Everton last season, it was determined Lacazette’s return of 36 was inflated by penalties.
Scouts also had doubts about his pace and physical presence, as well as his impact in big games.
Arsenal swooped for Lacazette after Atletico Madrid’s attempts to sign him were scuppered by their transfer ban.
Mourinho identified a replacement for Zlatan Ibrahimovic as his priority this summer – drawing up a shortlist of options that included Lukaku, Alvaro Morata and Andrea Belotti.
Lacazatte was quickly ruled out as a viable candidate.
Instead Mourinho believes Lukaku can establish himself as a world class centre forward in the mould of Didier Drogba and Diego Costa.
The 24-year-old Belgian has proved himself a prolific goal-scorer in the Premier League, with only Sergio Aguero and Harry Kane scoring more than him over the past three seasons.
