"The squad we have is amazing," said Saha.
"It is strong in every position. A few players did not even travel yesterday and we still have Paul Scholes and Gary Neville to come back..
"We are all aware this is a difficult period. Any team who has not got the right squad will struggle during that time because fitness-wise, it is very hard.
"Mentally, you have to be very strong to get through it. That is why the manager has been very clever."
