Bacary Sagna was a fantastic servant of the club for as long as he wore the Arsenal colours. Till his last day he was a consummate professional and probably one of the most committed defenders in our team, at a time when Koscielny had yet to fully blossom, and if I recall correctly Carl Jenkinson was our only other recognised right-back (2011-2013 period). It was his header, at 2-0 down against Spurs at the Emirates, when we were something like 10 points behind them in the league which just said "Fuck off", and triggered the comeback to 5-2 (the first one), in my first and till date favourite North London Derby.
Sagna left after seeing out his contract, for a big final payday, to what is nominally a rival club, but one against whom we don't have as much animus as say Tottenham or Man U, or Chelsea. Sure, he may not have loved Arsenal, he probably isn't a fan, and he may not go down as one of the Arsenal greats. But he served the club admirably, and is a player that left the club honourably. I don't think it makes much sense to have him back given his age and his qualities won't fit the current shape and outlook of our team, but I wish him well wherever he goes.
Sorry if this seems a bit ranty, but I suppose he's a player I like
