Well if you want a good tactic for Martins I suggest a 4-4-2 with Martins set as a target man with playing the ball to his feet. Also set your stle to counter-attacking, so youll get the most out of his pace. With that I reommend a good target striker (Bendtner...) when youre not on a counter and use your wingers(Duff,Milner, Solano) to provide for him. Make arrows in front of your wingers and have at least one or two defensive-minded players in the centre (Parker...). But if you still have Owen, then I dont know how will your game work, because then it would be a too one-sided tactic with two more or less similar players. |
