As they near closer to the club's 20th domestic title, Manchester United have nothing to be ashamed of.
That being said, this season could have been even more special than it already has been.
For United, really special would be achieving the elusive treble, where the EPL, FA Cup and UEFA Champions League are all won.
Since then, however, United has seen their hopes of triple glory vanish, uncharacteristically failing to close out games in FA Cup and Champions League play.
Against Real Madrid, their 2-1 aggregate lead in the second leg slipped away as goals from Luka Modric and Cristiano Ronaldo shocked the United crowd and bounced them from the tournament.
Later, at Old Trafford again, the Reds gave up a 2-0 halftime lead to Chelsea, forcing a second leg at Stamford Bridge which they went on to lose.
Considering the position they were in six weeks ago, United's season has become at least a mild disappointment, and has certainly spurned plans for Sir Alex to retire at the end of this campaign.
Sure, Sir Alex could certainly finish his illustrious career after this season and have no regrets.
For starters, soccer is his passion, as he's been managing—with much success—for 39 years.
That sort of passion will always leave him striving for more success, as he won't be fully satisfied until the club have regained their status as the world's best team.
With their current club, which has an aging back line (three members of it are at least 31) and a somewhat inexperienced goalkeeper (David De Gea is 22 years old), that task may not be possible.
Don't tell that to Sir Alex, though, who is without a doubt one of the world's best managers, and known for getting the absolute best out of his players.
Aside from his passion for the game, Sir Alex will not want to exit soccer with the sort of unfinished business that has been piled on during the course of this year—notably the squad's disappointing exits from the Champions League and FA Cup.
His desire to continue coaching is shown by the following quote from The Daily Mail:
I think it’s important to work and I’m entitled to work. Some people do not want to work but I want to continue working. Retirement is for young people.
Ultimately, Sir Alex's United squad haven't achieved a treble since 1999, and may never do so again.
How many more years do you think Sir Alex will coach?
But for the Reds' longtime boss, it won't be for a lack of trying.
Don't say goodbye just yet.
