Manchester United boss Erik ten Hag is hopeful Lisandro Martinez enjoyed a watershed week in his career,
The Argentina defender impressed for Monday's victory over Liverpool.
Ten Hag said: "It's a great habit [to be a warrior]! [Smiles] That's the way he is.
"Not everyone is the same, don't get me wrong, but we want a fighting team and we have to construct a team that is hard to beat, and from there on we will win games."
Ten Hag also said: "Of course the atmosphere after such a win is great and also from that game you can take lessons – you have to get into a season and to get into a season is always hard.
"Not everything will work 100 per cent and therefore you have to work really hard to get that done in terms of individuals and especially as a team to get the right cooperation. So from game to game you need to go in and start from zero and you have to win that game. There is a good spirit, we are ready for this game and we have to collect the points there."
