Both sides clash at The Liberty Stadium in South Wales today.
The Reds make the trip to South Wales on the back of a 1-0 Europa League semi-final defeat at Villarreal, which greatly jeopardises their hopes of reaching the final.
Manager Jurgen Klopp has made it abundantly clear where his priorities lie in recent weeks, often making wholesale changes for Liverpool's Premier League outings with a view to preserving his side's hopes in Europe.
Consequently, Gray feels that the German manager will make a raft of changes once again today, tipping the Swans to capitalise on the much-changed Merseysiders.
"A rare early game on a Sunday. Swansea weren’t up to much last week and Leicester absolutely destroyed them. Newcastle did the same to them the week before, it’s like they’ve gone into autopilot now that they are safe from relegation," he wrote on Paddy Power.com.
"Normally, I’d have Liverpool to win this. But Jurgen Klopp knows that he can’t make the top 4 of the table so he’ll put all of his eggs in the Europa League.
"I don’t believe we’ll see any first teamers on Sunday against the Swans. So I’m going for an upset at some decent odds."
Although Liverpool have indeed made plenty of changes recently, it has had little effect on their league form, with Klopp's side unbeaten in five outings - winning three of them.
But with their Europa League hopes hanging in the balance, the players' mentality might well be different this time around and Swansea, who have shipped seven goals in their last two games, might fancy themselves.
