Tottenham boss Mauricio Pochettino left out Ben Davies for the goalless draw against Swansea because of concerns over an ankle problem.
The Wales international started on the bench as Heung-Min Son played as a makeshift left wing-back and Pochettino said he wanted to rotate the team.
“He got a big knock on his ankle against Borussia Dortmund,” Pochettino explained.
“For different reasons we needed to rotate because we have a lot of games ahead.
“But I think one player is not the key to winning or losing. When you have 25 players you can use everyone.”
Spurs were left frustrated as Harry Kane hit the bar and Swansea keeper Lukas Fabianski made a string of good saves to leave the hosts still winless at Wembley in the Premier League.
Pochettino said: “I am happy with the performance but disappointed with the result. We created lots of chances and deserved more.
“Maybe it is Wembley. We have spent one season talking about this but, in the end, what can we do?
“We have to play here. We have to put White Hart Lane in the past.”
