Napoli are top of the table after a victory away to Milan, but footage has emerged showing Hirving Lozano very irritated with the coaching staff at the latest snub.
The Partenopei won the match with a Matteo Politano penalty and Giovanni Simeone header at San Siro on Sunday evening.
Mexico international Lozano was available again after injury, but remained on the bench, as Alessio Zerbin was preferred to him when Politano went off injured.
After the final whistle, Lozano was caught on camera refusing to look at Luciano Spalletti’s assistant manager Marco Domenichini, then pushing the staff member away when an embrace was attempted.
Spalletti was in the stands sitting out a touchline ban.
Lozano has been rather overshadowed this season by the arrival of Kvicha Kvaratskhelia and good form of Politano.
