MANCHESTER CITY legend Sergio Aguero believes Manchester United are among the "biggest threats" to his former club's Premier League title bid.
City are fourth in the Prem table with five points separating them from leaders Arsenal and four away from Liverpool and Aston Villa, who are second and third respectively.
This comes after a poor run that has seen the Treble winners falling off the pace with only one win in their last six league matches.
However, Aguero is not giving up on the Citizens and still considers them favourites to win their fourth consecutive title.
The legendary striker also doesn't expect in-form Arsenal or Liverpool to overtake the Manchester giants.

In fact, the Argentina great believes United, Newcastle and Tottenham pose as a much bigger threat.
That is despite the fact the Red Devils are enduring a disastrous Premier League campaign that saw them dropping to seventh place, with 11 points separating them from the top.
Aguero told Stake.com: “You can never sleep on Man United at this stage of the season,
"They are one of the biggest threats to Man City’s Premier League title.
"I also think Tottenham are title contenders, who have improved a lot under Ange Postecoglou.

"Even despite their ups and downs, Newcastle are also in with a chance of the title as they always put up a fight.”
Newcastle and Tottenham have also been dealing with an injury hell, which led to an early Champions League exit for the former.
United are also out of Europe's elite competition after finishing bottom of Group A behind Copenhagen and Galatasaray, who ranked below table-toppers Bayern Munich.
