Roy Keane has questioned the courage of Aston Villa's players after last night's 1-1 draw at Nottingham Forest.
The result has left Gerrard under pressure.
Former Aston Villa assistant manager Keane said on Sky Sports: "If Gerrard gets to January and these players are not producing, does he have to change them?
"I could not believe how bad Villa's attacking players were. They have quality but it's the lack of quality to try something. They lacked the bottle to try and hurt Forest - that comes down to the players.
"Gerrard has to be under pressure because they are not winning games, and they have a tough run of games. That is not good enough for a club like Aston Villa."
Also speaking on Sky Sports, Gerrard's former Liverpool team-mate Jamie Carragher added: "On paper they have four or five good attacking players. Coutinho is a shadow of his former self, he is a million miles from what he was. He looks like a five-a-side player, the pitch looks too big for him. The game looks too quick, the other players too powerful.
"Villa look like a very organised team but are they waiting for someone to bring that moment of brilliance."
