At first viewing it seemed like ball was played across the box but, replays showed Sancho was actually playing it back to Martial but a deflection took it across the goal. He definitely could increase his numbers with a bit more playing the poacher. Was watching Owen and Cole give their views on yesterdays' game and when it came to Martial, both were harping on he isn't what we need because he is not in the box, he is dropping deep and wanting the ball, that he should be in the box and not worry about the pretty football and just get tap-ins. Kept going on about Halaand who barely touches the ball and just gets in positions to score the goals.
But, that's completely ignoring ETH vision for how he wants to play, which is not a striker that just sits around waiting for a chance at a goal. He had that in Ronaldo. It's why it's quite clear that we play better when he is on the pitch because of his ability on the ball and link up with other aided by his hold up play.
If he stays fit though, he will have to add that dimension of breaking his neck at times to get into the 6 yard box, trust that the crosses or ball will be there, think ETH/Benni will work on that with him if they do manage to get his fitness in check.
