Southampton have been dealt an injury blow after Danny Ings was forced off through injury in the first half of their clash with Manchester City.
The visitors went in front after 16 minutes when Raheem Sterling finished after Kevin De Bruyne's measured ball across as Pep Guardiola's charges held out for a 1-0 win.
Ings had a shout for a penalty on 27 minutes when he headed wide before Ruben Dias made contact with the England striker. However, Mike Dean was not interested and VAR did not intervene.
Saints boss Ralph Hasenhuttl had grown frustrated during the game after feeling that several challenges on his men went unpunished and he became more exasperated when his talisman went down off the ball five minutes before the break.
