Manchester City regained its competitive edge after winning at St. Mary's at Southampton (1-3) to regain second place in the English Premiership in its final game of the year.
The whole of the Spanish coach Pep Guardiola, who had suffered three defeats in his last four games, was reunited with the win against a rival threatened by the decline, who paid his errors in the final stretch of the first part.
It was David Silva, a pass from the Portuguese Bernardo Silva, which facilitated the visitors triumph with the goal he scored in the ten minutes although Southampton balanced the situation in the 37th thanks to Pierre Hojbjerg.
However, the locals lost the course of the shock in the added time of the first half. First with the own goal by James Ward Prowse and then with the goal scored by the Argentinian Sergio Agüero, who headed off a pass to the Olexandr Zinchenko area.
Southampton, unable to return to the fight in the second half, ended the game with ten players for the expulsion, in the 85th, of Pierre Hojbjerg.
Manchester City will start the year with the visit next Thursday of the leader Liverpool. It will be a key clash for the champion, now second in the table but seven points from the whole of the German Jurgen Klopp, who on Saturday thrashed Arsenal (5-1).
