One thing that has really pleased me about ETH is that he's wanted to bring in players with the right character. Casemiro, Martinez and Antony are all the kind of fighters that you want in the team. United have too often been passive, or even too nice, at least since Jose left.
Since ETH is a manager who is clearly into the tactical and technical aspects of the game, its great to see that he also understands how import that fighting mentality is. My biggest worry about ETH before he joined us was whether he would struggle to turn the mentality of the club around, since every Premier League game can end up as a real battle. But with his purchases & team picks so far, I'm thinking he gets this just as much as the other stuff.
