BBC Sport - Southampton 3-1 Swansea: Saints need to improve - Ronald Koeman

Saints need to improve - Koeman

Southampton Manager Ronald Koeman says his side must do better despite a "clinical" 3-1 win over Swansea at St Mary's Stadium.

Virgil van Dijk's first-half header put Southampton ahead going into the break, before goals from Dusan Tadic and Sadio Mane sealed the victory.

The Saints conceded a Gylfi Sigurdsson penalty in the 83rd minute, but have only lost one of their seven Premier League games against Swansea.
