Ronald Koeman has dropped Sadio Mane from Southampton's starting XI for Saturday's trip to Norwich City after the attacker turned up late for a second time.
The Senegalese was similarly omitted in February when he failed to arrive on time for a Premier League clash with Liverpool.
Mane has been named among the substitutes at Carrow Road.

Mane has scored three goals in 19 top-flight appearances for Southampton this season.
