Indeed, the South Coast side beat the Cherries 2-0 and were rarely troubled at St Mary's but Wanyama's second-half sending off threatened to hand the momentum to the visitors.
And yet many felt the 24-year-old performed brilliantly before he was dismissed...
|V Bournemouth||Tackles||Interceptions||Fouls||Minutes Played|
|Virgil van Dijk||2||5||1||90|
As Opta stats show, Wanyama matched Virgil van Dijk defensively for Southampton, winning both as many tackles and interceptions as the big centre-back.
Steven Davis won more tackles, while Cedric Soares won more tackles and almost matched Wanyama in terms of interceptions.
But it was in the fouls department that the 24-year-old overstepped his mark, committing three fouls and earning a booking for two of them.
That left Southampton fans split on Twitter. Many defended the powerhouse midfielder and suggested he was simply fulfilling his role of 'enforcer.' Others were frustrated that Wanyama let his team down and felt Ronald Koeman should have substituted him as he was a red card 'waiting to happen.'
Here's a selection of the two sides of the debate that got supporters talking after the game on Twitter:
Up to the point of him getting sent off, Wanyama was fantastic. Cedric excellent as well! #saintsfc— Matt James (@mattjamesy) November 1, 2015
Thing is with wanyama is that he is there to do that sort of thing. #saintsfc— lenny (@lennysaints) November 1, 2015
Unsure why fans applauded Wanyama for being sent off and potentially helping them back into it #saintsfc— Ed Downs (@Sainted7) November 1, 2015
Completely different second half, excellent subs from Eddie Howe. Koeman should have subbed Wanyama, red card waiting to happen #saintsfc— Matt Ingram (@mdingram1) November 1, 2015
At least Wanyama's stupid red didn't cost us that #SaintsFC— Lee Myers (@leemyersSfc) November 1, 2015
