Jamie Carragher has blasted Manchester City's defenders for their display in the club's 2-0 defeat to Stoke City at the Britannia Stadium.
Marko Arnautovic scored twice to guide Mark Hughes's men to the three points, with Carragher pointing the finger of blame at Bacary Sagna and Martin Demichelis.
The former Liverpool centre-back has also suggested that City may still need to invest in more defenders due to the struggles of Nicolas Otamendi and Eliaquim Mangala in the absence of Vincent Kompany.
Carragher said on Sky Sports' Monday Night Football: "Of course they miss Kompany, but all those players are in their thirties. And in terms of City and the bigger problem going forward, they have spent big money in the attacking areas in [Raheem] Sterling and [Kevin] De Bruyne, because they felt they lacked pace. And I think they have both done okay, they have both done well.
"I think they may have this problem again in the summer with these because of the age of those players and the youngest one they have got is Mangala, who is not good enough. He has been here 18 months and had his time and I think City know that as well; they tried to move him on to Valencia.
"And Otamendi has come in as well, another one in his twenties, who is still yet to show us what we think he may be capable of. But he is struggling as well. So it looks like in the summer they could be needing one or two players, but you think of the money they have spent, £70m on two centre-backs, and they can't play without Kompany."
City dropped down into third place in the Premier League following their defeat to Stoke.
