Saints manager Mauricio Pochettino says he has a fully fit squad to choose from for the trip to Manchester United.
Confusion reigns over Artur Boruc and his supposed injury.
The keeper was left out of the Poland side because of an apparent hamstring injury and later a photo of him with his leg strapped was posted on the internet but Pochettino insisted he has been fine to train since returning to the squad.
"He is OK," said Pochettino.
"He has been training well and we are hoping he is going to be perfect for Saturday’s game."
Of Luke Shaw and the rest of the squad he added: "The last few days he has been training well. He has been OK.
"We hope that he is going to be perfect and physically fit for the game against Manchester United.
"The rest of the squad arrived OK. Everybody is fine.
"The only one who hasn’t arrived is Gaston Ramirez and we think he is going to arrive tonight.
"Some are more tired than others because of their long travel in international commitments but they are fine."
