BUENOS AIRES, Oct. 20 (Xinhua) -- Boca Juniors extended their winless run to three matches across all competitions with a goalless home draw against Rosario Central in the Superliga Argentina on Saturday.

The hosts dominated possession but struggled for potency in attack, with just three shots on target to Rosario's two.

Former Manchester United, Manchester City and Juventus forward Carlos Tevez was introduced as an 81st-minute substitute but failed to make any meaningful impact.

Rosario were reduced to 10 men in second-half stoppage time when midfielder Joaquin Pereyra was shown a second yellow card for a rash challenge on Sebastian Villa.

The result at La Bombonera left the defending champions fifth in the 26-team standings, five points behind leaders Racing Club, with four wins, three draws and two losses.

In other Superliga Argentina matches on Saturday, Lanus beat Patronato 3-1 and Godoy Cruz overcame Aldosivi 2-0.
