Barcelona: Aguero responds to retirement rumors

Sergio Agüero is "staying positive" as the Barcelona striker waits to discover if he will be forced to retire due to a heart problem.

Reports from Catalonia emerged on Friday suggesting Agüero may have to bring an early end to his playing career because of an irregular heartbeat.

The Argentina international first experienced chest pain in Barça's draw with Alavés on October 30, which the club later confirmed was down to a heart arrhythmia.

After undergoing tests, Agüero – who has started just two games for the LaLiga giants since arriving on a free transfer from Manchester City – was ruled out for three months.

Catalunya Radio reported the problem is worse than first feared and Agüero may have to hang up his boots at the age of 33.

However, the former Atlético Madrid striker took to Twitter on Friday to deny that is the case, with a decision on his future not being made until at least February.

Agüero: I am following the indications of the club's doctors"

"Given the rumours, I can say that I am following the indications of the club's doctors, doing tests and treatment and seeing my progress within 90 days. Always positive," he said.

Agüero had been carrying a separate injury upon joining Barça that has restricted him to only five appearances in all competitions this term, totalling 166 minutes on the field.

He scored his one and only goal in last month's Clásico showdown with Real Madrid, the late strike proving to be nothing more than a consolation in Barca's 2-1 defeat.

Prior to joining Barca, Agüero scored a club-record 260 goals in 390 appearances in a glittering decade at Man City, including their famous last-gasp winner against QPR in 2011-12 to clinch the club's maiden Premier League title.

The Buenos Aires-born forward also previously spent three years with Independiente and five with Atlético.
