Sanchez could play some part in Saturday's match at Swansea City after recovering from a hamstring injury, while Grealish and fellow midfielder Adama Traore should be available for selection after the international break.
Aston Villa are ready to welcome Carlos Sanchez back for Saturday’s trip to Swansea City, manager Remi Garde has revealed at his pre-match press conference.
Sanchez, 30, has not played for Villa since January’s 2-0 FA Cup third round replay win over Wycombe Wanderers when he was forced off at half-time after suffering a repeat of a recurring hamstring problem.
The Colombian midfielder has missed a total of 14 games across all competitions since late December as a result, but he is now back in full training and set to be available for the weekend.
However, given his lack of action over the past three months, Garde is unsure whether he can risk using the former Elche man from the start against Swansea.
“Carlos should be available for selection,” the Villa boss told reporters. “You have to balance his comeback, though. He hasn’t been playing for a long time. You cannot expect to have the best from a player that has been injured for quite a few weeks.
"But on the other side, Carlos is a very experienced player and in that way it could be very interesting for the team."
Meanwhile, Garde also expects to have both Jack Grealish and Adama Traore back fit and available for selection after the coming international break.
Grealish has missed Villa’s past five matches since twisting his ankle in training ahead of last month’s 6-0 home defeat to Liverpool, while Adama has been sidelined for 10 weeks after breaking his foot in the 3-1 loss at Sunderland.
Both players will likely be fit by the time Chelsea visit Villa Park on 2 April, but Saturday’s Swansea clash has come too soon for either to make their comeback.
"Jack and Adama will not be available for this game,” Garde added. “But hopefully they will be available for the Chelsea game after the international break.”
Elsewhere, Gabby Agbonlahor is expected to be available for the weekend after sitting out Sunday's 2-0 loss to Tottenham Hotspur with a thigh issue, but there is still no timetable on when Libor Kozak [ankle] or long-term absentee Jordan Amavi [knee] could return.
