Both South American strikers have generated more than 50% of their team's goals this season, sparking controversy about how much the Citizens and the Gunners rely on them.

Sanchez arrived this summer to Arsene Wenger's team, while Sergio Aguero has been a part of the Citizens for quite some time. Both South American strikers have proved to be quite helpful for their teams, but neither side should rely on them too much, since both teams have become increasingly dependant of what each player does inside the pitch.

Alexis Sanchez has scored nine goals in the Premier League for the Gunners, adding three more in the UEFA Champions League. He has also handed out two assists in the local tournament, adding one from the European tournament. The Chilean has been involved in 50% of Arsenal's goals this season, proving he has been a key addition to Arsene Wenger's squad. With such an influence in the team's performance, Sanchez has been voted by Arsenal's fans as the Player of the month for the third time in a row. 

But if Sanchez's influence has been key to Arsenal's survival, Sergio Agüero's performance has proven crucial for Manchester City. The Argentinian leads the Premier League in goals scored with fourteen in the same amount of games. "El Kun" has also dished out three assists, having a direct influence in 55% of his team's scoring plays in the local tournament.

Added to his influence in the EPL, Agüero has kept the Citizens' hopes alive in the UEFA Champions League. With five goals and one assist, including a hat-trick in their last match against Roma, Agüero is key to Manuel Pellegrini's survival as head coach for the Sky Blues, since his project has not proved to be successful when playing abroad. Manchester City's fans hope Agüero can stay fit, because the team has proven to be quite dependant of what the former Diego Maradona's son in law can do for them.

Their performance this season has even made trolls have their day talking about their teams.
