I mean, Gareth bale isn't 2 footed and he's done ok.If I was fortunate enough to pull on the white shirt, I'd give 100% (or maybe even 110%!).
Unfortunately it's not enough.
There are myriad qualities demanded of a modern pro footballer. Towards the top of this list would be two-footed and available for selection.
Injury wise, Erik has suffered but not all players give 100 percent and he does and has earned a bit of love and a bit of niceness now he appears to be leaving....sissoko isn't gonna get anything tbh.
