Marcelo Flores is reportedly unhappy that he has been left out of Arsenal's pre-season tour to the United States with the Gunners set to play three friendlies.
Mikel Arteta's side flew out to Baltimore on Thursday to continue preparations for their Premier League opening weekend trip to Crystal Palace. They will face Everton, Orlando City and Chelsea during their tour of the States.
However, the squad has raised a few eyebrows. Midfielder Thomas Partey is in the travelling group having missed last week's trip to Germany, where they defeated Nurnberg in a friendly on Friday, while goalkeeper Bernd Leno has been included despite being close to a £10m switch to Fulham.
