Chelsea, Arsenal and Tottenham Hotspur are all reportedly monitoring Sergio Aguero's current position at Manchester City.
The Argentine forward has scored 11 goals in 12 appearances for Man City this season, but was left on the bench for the club's Champions League clash away to Barcelona last week.
Aguero did come back into the team for last weekend's Premier League clash with Southampton, but was again on the bench for the League Cup defeat to Manchester United at Old Trafford on Wednesday night.
It has been claimed that the striker has a strained relationship with head coach Pep Guardiola, although the Spaniard said earlier this week that he wanted Aguero to stay at the Etihad for "a long time".
According to Don Balon, Chelsea are the club paying the closest attention to developments in Manchester, but Arsenal and Tottenham are also considering moves for the 28-year-old.
Aguero has scored 147 times in 220 appearances for Man City since joining the Premier League club from Atletico Madrid in the summer of 2011.
