3 Fa cups in the last 4 years and a possible europa league win this year. Yeah what a shit legacy to leave behind in his final few years.
From where we are 3 FA Cups in 4 years would be fantastic but from an Arsenal point it's the 3rd most important competition of the 4 they've entered over the years, apart from last year when they didn't qualify for the Champions League and probably more seen as a bare minimum than anything else.
I don't think there's many fans too upset he's going, he's built a legacy and will rightly be considered a legend. But they've watched as he's slowly fallen down the league, constant failure in the Champions League and despite two billionaires with the bulk of the shares have watched as Liverpool come back to the top four, Man City pass them and win league titles and bitter rivals Spurs regularly finish above them and this season struggling to even stay ahead of Burnley.
FA Cups are great but it's been so devalued over the years it's not where a club like Arsenal would see themselves, they were challenging and winning league titles when he took over. He's managed one Champions League final in about 20 attempts and not got past the last 16 in the last 7 attempts. Like I said, he'll still leave a legacy but it would have been far less tainted if he'd gone 5 years ago regardless of the FA Cup wins.
