Runaway Premier League leaders Manchester City will look to strengthen their defence in the January transfer window as they plan to compete for multiple trophies in Pep Guardiolas second season.Injuries to John Stones, Vincent Kompany and Benjamin Mendy have left Guardiola with very few options and he said that he and the club will look to fix that come January if needed.In that department we have too few players and to handle all competitions we are in trouble, real trouble if this is the case. But I cant assure anything. We are going to see what will happen in January, Guardiola told a news conference on Tuesday.Maybe we are thinking of looking at another central defender because of Vincents problems, John Stones is four or five weeks out. And we miss an important player like (Benjamin) Mendy.
