Manchester United fullback Luke Shaw says the players know manager Erik ten Hag makes his team selection on merit.
Shaw has insisted that having competition in every position is essential, admitting that performing well in training is vital under Erik ten Hag.
''I think competition is always healthy, everyone wants to play every game but you understand the manager only can pick 11,'' he said.
''I think the new thing here with this new manager is if you are playing well and not training well, you are not going to be in the team. Everyone knows that and it keeps everyone on their toes. No-one can really relax and think they're going to play every game because with this manager you're not going to do that if you are not playing well.''
The 27-year-old, who joined United from Southampton in 2014, also insisted that he can see the team progressing under Ten Hag's management.
He added: ''I can see a lot of progress. I can see that the team is enjoying the new ideas and wanting to work with the new ideas,'' began Shaw, speaking to club media.
''He has brought a lot more intensity, a different structure and a structure that we now know what he wants us to do, which is a big help."
