Morgan Schneiderlin has warned Southampton fans not to get carried away with their flying start.
The France midfielder says their toughest tests are still to come.
He said: "It's a surprise to have got off to the best ever start in the league after going through so many changes in the summer.
"The coaching staff changed, a lot of players left so of course it's great for us to be in such a good position after five games, but it's only five games of a long season and we need to keep going.
"We had a very good start last year as well but it was difficult after going through a hard time in December and after that it was difficult to get back up the league. We're going to try to be stronger in that period."
