I'm sure you're right about cook and lerma. It's how change happens, the pace of it. Change the team while retaining balance. Key in midfield is someone running it. Surman holds the space well. He is calm and tidy. Gosling is a great harrier, and interceptor. Both get the odd goal, something arter stopped doing. Arter hasn't changed, 2 yellows in 2 games shows that. One should have been a red. An Arter who doesn't lose it is what is needed. (Pauses and looks at Lerma's disciplinary record).
I still think 3 in the middle is best against most teams. A triangle with one sitting deeper in almost a sweeper role, which is often what Surman does. I can see Ake doing that, but he is better where he is right now.
It has taken a long time to see Fraser and King develop into the players they are today. Wilson is still on that journey post injuries.
Rantie and Afobe never made it. Maybe Ibe will, maybe he won't.
It's going to be a huge change for Rico and Lerma. But it will come.
Chelsea will be interesting. I suspect he'll rest Brooks and I have a feeling he'll bring Ibe back. Wouldn't be surprised if Lerma came on with 30 minutes to go.
