You may have to wait til next season to sort those issues.
He tried to get a striker in and failed, and has only marginally improved Torres thus far.
A thankless task that one.
He tried to freshen up pivot with new blood and van ginkel got injured.
Be patient.
He is experimenting with a squad that is not his and has not got it right yet. He may need a summer transfer window and a full preseason to do so.
There again he is such a good coach he may even get it right before then.
If we had big problems we would be ninth not third
