Claude Puel believes Southampton's win over Watford was especially important due to the make-up of their fixture schedule this month.
Saturday's game, at Vicarage Road, was one of only two that the team is due to play during March.
That is because next weekend's originally-scheduled meeting with Manchester United has been postponed, due to the Reds' FA Cup involvement, while the visit to Spurs in two weeks is followed by an international break.
"It's difficult to stay two weeks now without playing," said Puel, after the thrilling 4-3 win over the Hornets.
"We will wait two weeks to play away at Tottenham and, after that, it is another two weeks with the international break. This is very, very difficult.
"We have only two games this month, after playing every three days since the beginning of the season – it's crazy."
Had Saints not beaten Watford – a result that moved them up to tenth in the Premier League – Puel believes the table could have ended up having a much less satisfactory appearance.
"It was important to win," he said. "For example, next week we cannot play, but the other teams can.
"Without a good success [against Watford] and the possibility to play the next week against Manchester United, we would see different teams before us on the table, so it was very important to win."
