Watford head coach Quique Flores has admitted that he will be forced to rotate his starting lineup over the Christmas period.
Between now and January 2, the Hornets have Premier League clashes against Liverpool, Chelsea, Tottenham Hotspur and Manchester City.
With four games on the horizon in such a short period of time, the Spaniard conceded that it is "impossible" for his players to feature in each of them.
"This is the first time I will ever manage in this type of situation," the Watford Observer quotes the former Valencia and Atletico Madrid boss as saying.
"The recovery of the players is going to be very important in the next two weeks, but I have a squad and I would like everyone to play.
"It is impossible for every player to play all the minutes in the next four games. Between Chelsea and Tottenham there will be no time for the players to recover, we have only one day."
Sanchez has guided his newly-promoted side up to seventh in the Premier League with 16 matches played.
