The Argentine saw his men move third in the Premier League with a 4-1 win over Hull City at St Mary's Stadium on Saturday, with goals from Morgan Schneiderlin, Rickie Lambert, Adam Lallana and Steven Davis.

"We could be our own worst enemy. We need to keep working with the same work ethic and humility because we will probably be getting a lot of compliments due to how we played [against Hull].
"We need to make sure that we manage those compliments in a good way and turn them into positive energy to keep up our performances.
"We can't let it get to our heads – we need to manage expectations and just keep doing what we are doing."
Southampton's next two fixtures see them travel to fellow top-four sides Arsenal and Chelsea in the Premier League.
