That’s not completely true Arsenal and city fans both have had players they’ve highly rated who pep and Arteta just don’t play as much as they’d like. People thought Pep underplayed Foden for a few years, barely played Palmer (and look what happened there) and Arteta was roundly criticised for not playing Nwaneri more when Ødegaard was out injured (even though he is 17).Using Maz as the no10 when Bruno was unavailable was the worst in the way ETH treated Amad. Even if ETH doesn't rate Amad in that position(which is surprising), that was an opportunity to try our 'better' academy players. That's what pep, arteta and co. does very well.
Regardless ETH was wrong to not utilise Amad
