Possible lineups for Luton v Man City clash

John Stones has urged Manchester City to keep their composure amid a worrying slump that threatens to derail their bid for a fourth successive title.
City's winless run extended to four league games on Wednesday as Aston Villa's 1-0 victory increased the sense of concern surrounding Pep Guardiola's side.
The treble winners were comprehensively outplayed, leaving Guardiola to admit he needed to "help" his "struggling" team. Trailing Arsenal by six points, Stones believes City can use the pain of their stumble to stop the rot in a tricky assignment at Luton on Sunday.
"We've been in these positions in previous seasons. I don't think we or everyone should be hyping about what is going to happen. We have to stay calm as a team."
Luton Town possible lineup: Kaminski (GK); Bell, Osho, Mengi; Ogbene, Barkley, Mpanzu, Doughty; Townsend, Adebayo and Morris.
Manchester City possible lineup: Ederson (GK); Walker, Dias, Ake; Stones, Rodri; Silva, Alvarez, Foden, Grealish; Haaland.
