At my cynical worst Tiote sold for £20m, Anita bought for £6.5m.
But in all honesty I don't believe that will actually happen.
Seems the most likely explanation though. I can't see Anita give up an improved contract, a starter position and CL football for a place on the bench. Tiote and him are pretty much mutually exclusive on the field.
Unless we play 4-3-3 with Anita and Tiote as the defensive pivots and Cabaye as the advanced midfielder with (Debuchy) and Santon bombing up and down each flank providing the width.
If that's the plan it would have been nice to even try it before the season starts.
Would have been nice to play Cabaye and Tiote together before last season started as well but it worked out ok.
