Sergio Aguero scores against Southampton as they won 3-0.Manchester City kept their top four hopes alive with an impressive 3-0 win over Southampton at St. Mary’s on Saturday.Goals from Vincent Kompany, Leroy Sane and Sergio Aguero were enough to give Pep Guardiola some respite after a slow first half.First HalfTwo teams in decent form and when Southampton meet Manchester City at this stage, a lot more fireworks are expected than what was served in the opening exchanges of this game, as although both sides did move the ball nicely enough, but there were hardy any real chances created in the opening periods.With the exception of a slew of corner kicks, there were hardly any real opportunities being created by either side. The first big chance of the match didn’t come until the 36th minute, when David Silva fired just wide of the right post from inside the box after being put through by Sergio Aguero.But that would be the first and only real chance of the first period before the referee sounded the whistle for the halftime break. Second HalfUnlike the first half, this second period started better as City began to show more control in the game. Although Southampton were trying to give as much as they got, but it was Pep Guardiola’s side that was bossing possession and dictating the pace of the game.And all that possession would pay off shortly after, when Silva’s corner kick found the head of Kompany, who powered past Frasier Forster to give City what was a deserved lead.That goal upped the tempo of the game more, with Southampton making offensive changes with the hope of leveling, but it was still City who was in charge of play, dominating possession and just when it was looking like nothing much would happen, City found the back of the net once again.The impressive Sane found space inside the box after being freed by Aguero, and the youngster put the ball in the bottom corner to increase city’s lead, making it 2-0 at this point. And just three minutes later, they were three goals up, Kevin De Bruyne planting a cross on Aguero’s head, and the Argentina striker headed past the Southampton goalkeeper and it was 3-0 to the Citizens.And that would be the last real piece of action as Guardiola maintains his top four hopes with this win.
