Vincent Kompany’s first goal in 20 injury-ravaged months helped Manchester City to a 3-0 win at Southampton on Saturday, lifting the team to third in the Premier League.Kompany marked his latest return to the City defense by heading a 55th-minute opener before Leroy Sane and Sergio Aguero also contributed goals.”It’s always a long journey back,” Kompany told BT Sport television. “I would like to have been injured less in my career but every single time I put in the hard work I don’t really complain too much about what’s happening to me and I just carry on.”When this happens (scoring), I feel I am giving something back to the fans. I feel like I’m finally giving something back to the team as well.”City wrapped up the win with two goals in three minutes.David Silva sent Kevin De Bruyne through and the midfielder squared for Sane to sweep past Forster for his ninth goal of the season in the 77th minute. Then De Bruyne chipped the ball into the Southampton six-yard box where Aguero headed in at the far post as City eased to a second successive win.The 2012 and 2014 champions are looking to lock down a return to the Champions League and Pep Guardiola’s side moved a point ahead of Liverpool, which occupies the fourth qualification spot. Everton and Manchester United are six points further back.
