London trio monitor Sergio Aguero

London giants Arsenal, Chelsea and Tottenham Hotspur are all keeping a close eye on Manchester City striker Sergio Aguero. The Argentine's future has been put into doubt this term after he was benched for the game at Barcelona.

Aguero has been a chief contributor for the Citizens over the years having guided his side to two Premier League titles.

Spanish outlet Don Balon says the 28-year-old is weighing up his options for next summer after manager Pep Guardiola decided against offering him a start at Barcelona.

The Mancunian giants were eventually humbled by a 4-0 scoreline in the Champions League encounter with Aguero earning little time to impress at Camp Nou.

Manager Pep Guardiola has since rubbished speculation over his player's future, but according to sources, Aguero is yet to form a solid relationship with his coach.

Aguero has netted nearly 150 goals for Manchester City in all competitions.
