I have no preference for any player tbh.
An AMF's job is to create chances on goal, which he does well. If he gets the ball 5 times and creates 5 chances and works hard off the ball then he has done his job. That's the difference between the bullshit possession based measure and the relevant efficiency measures.
I don't want him to chase possession as that's not what attacking playmakers do, and that is why most AMFs always seem to drift in and out of games even though they work hard off the ball.
Firstly, we were never in commanding positions because our game plan was rubbish, secondly a CAM needs to link up and given his lack of on field time I think he did well, especially with Fitzy. If they were smart they would have played him as a traditional position rather than Cahill and instead of making him chase the ball out wide all the time. Just remember that our attacks were wide 90 % of the time and setup to bomb into the box with Timmy running in, so as a result there was no CAM role so to speak. But what he did do well was link with the forwards and track back to stop the opposition's DM. And the slowness of ball movement out of defence was a joke.
If a traditional CAM role is in our game plan then Caceres has the game. He needs to be played for the most part of 90 mins at least up until Christmas to get a fair indication of if he is average or a match winner. He at least deserves an opportunity, and if he doesn't take the opportunity then trade him off in January.
