The Argentine was beaten to a place by Tottenham Hotspur's Harry Kane and Chelsea's Diego Costa. Kane deserves his spot, his transformation has been one of the most intriguing subplots of the season, but Costa probably doesn't; he's been good, but also incredibly annoying.
Personal opinions aside, what makes the PFA's choice particularly perplexing is Agüero's record this term. The Manchester City striker has outscored both of the players that beat him to a place, netting six more goals than Costa and five more than Kane. Goals are pretty important, but I'll accept that they aren't everything, which makes his exclusion that little bit more baffling. Agüero has registered more assists, more shots on goal and has completed over 30 more take ons than both of his scandalously fortunate competitors this season, but still no place.
I mentioned above that Kane deserves his place, so I'll lay off him for the remainder of this piece, but Costa isn't off the hook.

Of course, it's not his fault that he was included in the team. The blame lies with the Professional Footballer's Association who seem to base their selections on what is expected rather than solid, honest statistics. Harsh, perhaps, but Kane was a bit of a nobody before the 2014/2015 campaign and his dramatic rise to the top of the goalscoring charts has been tremendous. The PFA couldn't leave the young Englishman who has defied the odds out of their team.
As for Costa, he's notched up an impressive goal tally in his first season in the Premier League - a division famed for its muscular defenders and physicality. Nineteen goals in 24 games is an admirable return for a newbie, but does that make him more deserving of a place in the Team of the Year over a man who has scored six more goals than himself? If the PFA are operating on that logic, why was Agüero overlooked in 2011/2012 when he bagged 25 goals and scored the crucial goal in his first and City's title winning season?
I doubt Sergio has lost any sleep over the matter. Making the Team of the Year is nice, but not particularly important for a bloke earning around £200,000-a-week. The 26-year-old will be much happier scooping up the Golden Boot award at the end of the season. The reason I complain is because it would be nice for Manchester City fans to see a little recognition from the PFA for our superb little South American.
City fans are understandably concerned about the issue, but not one of us can claim that Agüero is underrated. He's perpetually peppered with praise from the British media and receives applause from top football managers on a regular basis. Before his side's clash with the Blues back in October, Tottenham boss Mauricio Pochettino said that watching his fellow Argentine was "like listening to classical music composed by Mozart". Praise like that is common for the striker - people know just how good he is.

But sadly, the PFA continue to ignore his excellence. In their best three seasons in the Premier League, legendary strikers Thierry Henry, Ruud Van Nistelrooy and Didier Drogba netted 72, 69 and 61 goals respectively. Sergio Agüero's tally currently stands at 67 and with two games left to play this season, that total is likely to rise.
Regardless of what the PFA might think, Sergio Agüero is destined to go down as a Premier League great.
