About Sonny's best position.
I agree that he looked better without having to track back the opposite RB. However, we won't be able to play every game with two strikers (even though this could be our best formation against specific teams). I don't think it's a drama for Sonny. I counted his highlights since the restart, playing as a traditional winger:
One good header, from a great position to score the 2-0, against United. One goal against West Ham disallowed by offside (so close!); also assisted Harry Kane's goal. Gave another goal to Kane against Sheffield and was in a great position earlier to score from a Aurier's cross - intercepted just before his shoot. Three very dangerous shoots against Everton.
His final production is fantastic, no matter the position he plays. And I don't think tracking back is really the problem. In my opinion, the only problem when he plays as a left winger is that, in Jose's system, the RB bombs forward, while the LB stays back, leaving the left winger isolated. It doesn't affect his numbers that much, but it would be better to have Sonny playing closer to the striker.
So I think that, when we play a 4-2-3-1 or a 4-3-3 (our "normal" formations) Sonny should be used as a right-winger instead. In our system, the right winger plays from the right to the inside - there's a very offensive RB just behind him -, close to the striker and close to the number 10/second striker.
It was in this role that Jose got the best of Eto'o, at Inter. I think it could work very well for Sonny.
