Pep Guardiola suggested he could make a change to Manchester City's defence when they entertain Liverpool in the second leg of their Champions League quarter-final on Tuesday.
City have conceded six goals in their last two outings, going down 3-0 at Anfield in the first leg before throwing away a two-goal lead to lose 3-2 versus arch rivals Manchester United on Saturday, a match in which they would have clinched the Premier League title with a win.
Nicolas Otamendi and Vincent Kompany were the centre-back pairing on both occasions, and Guardiola is considering an alternative defensive duo.
