Yaya Toure shrugged off John Terry's claim the title-race pressure is all on Manchester City by leading Manuel Pellegrini's men to a 3-1 victory at West Brom.
Chelsea captain Terry said "it's going to be tough" for his side's rivals to stay close to the pacesetters after the Blues took a temporary six-point Premier League lead with a 2-0 victory over West Ham.

Toure and company had other ideas however, the Ivorian netting a penalty to send City 2-0 up in just 13 minutes at The Hawthorns following Fernando's opener.
