Southampton boss Ronald Koeman says Premier League clubs must show more patience with managers, after Tim Sherwood was sacked by Aston Villa.

Sherwood is one of three Premier League managers to lose his job already this season, and Koeman believes clubs should show more patience.

"Too many clubs are changing the manager too fast," the Saints boss said at his pre-match press conference.

"Most of the time to change the manager is not better for the team or better for the club. Sometimes, yes, but...

"It's always disappointing because all the managers know it's a difficult job with a lot of pressure, and sometimes you need understanding and support.

"To make these kind of decisions after 10 games is, in my opinion, too fast."
