His defence is very narrow with 3 DC in, you should try to exploit this with wide players, you definatley need DR, DL, ML MR for balance and this may expose his flanks when you have the ball!, as he is only using the DML as cover for the left then yeah you can try and use an attack mainly down the right but I dont like playing game like that I prefer a balanced look to my teams so I would go with a 4-4-2 or 3-1-4-2, depending on you players you have available.
