However, Benitez was not forthcoming when asked if one or all of the players may be involved in the game.
"The international break is an opportunity to bring back players," said Benitez, per the club website.
"Alex Iwobi was training and [so were] Digne and Coleman – that is good news for us – they have started training with the team.
"The others are improving and we will see in the week how they are.
"Lucas had an issue and for two or three days was under treatment but he has started training.
"Fingers crossed [for Yerry Mina], hopefully everything will be fine in the last game, then we will see [if he is ready for West Ham].
"Every day when they [Ben Godfrey and Salomon Rondon] train, they are improving.
"Salomon is scoring goals in the training sessions and Ben is defending really well.
"This time will benefit everyone but especially these players who were not fully fit."
