Manchester City's defensive woes have increased after John Stones was ruled out for a few weeks because of a hamstring injury.
Stones was injured in City's 2-1 loss to Manchester United in the Premier League on Saturday.
City manager Pep Guardiola gave the injury prognosis on Tuesday, a day before the team plays Dinamo Zagreb in the Champions League.
City is short of numbers in central defence, with long-time captain Vincent Kompany leaving in the off-season - and not being replaced - and Aymeric Laporte sustaining a serious knee injury at the start of the season.
Guardiola has been playing Fernandinho, a defensive midfielder, at centre back.
With Stones out, Nicolas Otamendi is the only other senior player available to partner Fernandinho for a busy month when City plays in three competitions - the Champions League, the Premier League and quarterfinals of the English League Cup.
