West Ham's defensive frailties have been exposed in recent weeks to an alarming degree.
The Hammers have conceded seven goals in two matches against Swansea City and Burnley, two of the bottom four highest scoring teams in the Premier League.
If they can retain their status in the top flight then it would make sense for manager David Moyes to look to former side Everton this summer for a solution.
Michael Keane has failed to settle at the Toffees since his £25 million summer move from Burnley, and he could potentially be an outstanding addition for the Hammers.
Competition for places is high at Everton and The Times report the Toffees are planning a move for Manchester United centre-back Phil Jones this summer.
With Mason Holgate, Ramiro Funes Mori, Phil Jagielka and Ashley Williams all already competing for spots, Keane could potentially become expendable.
It would make more sense for Everton to let the ageing Jagielka move on and ditch Williams, but Keane's big price tag makes him vulnerable.
Keane showed at Burnley how good he can be, winning a place in the England squad, but his spot in this tournament's World Cup finals is in doubt.
The Mirror reported last month Everton are ready to ditch Keane this summer, and the Jones rumours lend weight to that possibility.
West Ham would be smart to test the waters over the 25-year-old, and offer him the chance to become the cornerstone of their flailing defence.
