Pep Guardiola concerned by Man City's wastefulness

Manchester City manager Pep Guardiola was frustrated by his side's profligacy in Saturday's 1-0 victory at Southampton and has warned his players they must develop a killer instinct in front of goal if they are to mount a successful title challenge.

Raheem Sterling gave City an early lead at St Mary's but Kevin de Bruyne, Bernardo Silva and Riyadh Mahrez all missed gilt-edged opportunities to drive home their advantage, a hallmark of City's season so far.

Guardiola's side has scored 19 goals in 13 Premier League games, just over half of the 37 it had netted at the same stage of the previous campaign.

"Our goal is to try and win games, to be up there as quickly as possible, as close to the top of league," Guardiola said on Saturday.

"But our momentum is not good up front. We will struggle if we don't break this situation and score more goals."

City is sixth on 21 points, eight adrift of leader Liverpool, which trounced Crystal Palace 7-0 on Saturday.

"We are far away. It's a lot of points," Guardiola told Amazon Prime. "Liverpool still have momentum. No doubts about how good they are."
