Jose Mourinho rejected the chance to sign Alexandre Lacazette for Manchester United after receiving negative scouting reports.
United emerged as potential candidates to sign Lacazette in June, with the club then having turned their attentions away from Atletico Madrid forward Antoine Griezmann.
Lacazette was first intended to move to Atletico this summer, but the Spanish club were hit with a transfer ban preventing them registering players until January next year.
It was then thought that the forward could stay at French club Lyon, but Arsenal moved in to sign him for a club-record fee earlier this month.
According to The Guardian, United turned down the opportunity to sign the 26-year-old before he moved to the Emirates Stadium.
Manchester correspondent Jamie Jackson writes that ‘Mourinho was informed of doubts regarding Lacazette’s suitability for the Premier League, his physical attributes and big-game mentality’.
Lacazette scored 129 goals in 275 games at Lyon, boasting a record of 100 goals in 203 Ligue Un games, and scoring at least 20 goals in each of his past four season.
United instead signed Romelu Lukaku for a British record fee of £75million on Monday.
