Ronald Koeman is starting to become increasingly frustrated with the number of players leaving the south coast club.
With a previous report from the Mirror stating that the Kenyan stalwart has just 18 months left on his contract at St Mary's, it seems an extremely high asking price. However, the Mirror suggests that the club have taken the firm stance in an attempt to satisfy their own manager, Ronald Koeman.
The Dutchman has become increasingly frustrated at the number of his key players that have departed since his arrival in 2014, and with Wanyama being linked with a switch to Arsenal - while Manchester United chase Sadio Mane (via Mirror) - the club's hierarchy have seemingly attempted to put the Gunners off a move.
The tactic may well work, as with Arsene Wenger closing in on a deal to sign Basel midfielder Mohamed Elneny (via The Guardian), he may decide that £20m is too steep for a player that, as things stand, will be available for nothing next summer.
And while that may prevent Wenger pursuing Wanyama during this window, it may just be delaying the former Celtic man's departure. And if that proves to be the case, Koeman's frustrations with the Southampton board may just boil over.
