How have I confirmed that? Show me. We've had this debate before. He may know what's required of a DM but he's not showing he knows what's required to be a CM. It's not about his ability. It's more down to his mentality and intelligence. I don't know whether it's down selfishness, instructions or a lack of understanding about the position for us.
Playing DM is a more restrictive/disciplined role and especially when we've taken off Coquelin. Ramsey would have to be really stupid to carry on going gung ho after seeing Coquelin subbed. It's like when Wenger has sometimes taken off our rightback and had a winger playing there place. I think Ox has had to play there after a sub. Even though he's an attacking player, he has enough sense to curb his attacks and runs forward.
CM you have more license to get forward and that's where Ramsey is going wrong. Just because you have that freedom, doesn't mean you should be so reckless. That's his main problem in that role. It's more a mental and intelligence thing. It's not technical. Take Santi as an example. He's attack minded but curbed that instinct and adjusts when playing CM because he knows a more disciplined and defensive duty is required.
