Manchester City are reportedly contemplating whether to switch their attention away from Napoli defender Kalidou Koulibaly.
The Premier League giants have been heavily linked with the Senegal international in recent months but they have failed to make progress with a bid.
Napoli president Aurelio De Laurentiis has recently suggested that there is reluctance on City's part to hold direct discussions regarding the centre-back.
According to Sport, City are considering their options, aware that they ideally need to sign another player for that position in the coming weeks.
Sevilla's Diego Carlos and Atletico Madrid's Jose Gimenez are both said to have been mentioned by Pep Guardiola and sporting director Txiki Begiristain.
Their respective clubs may also be willing to do a deal below Koulibaly's valuation, said to be in the region of £60m.
