Manchester United hero Patrice Evra is convinced of success from their two South American signings.
Evra says Antony will need time to adapt to Premier League demands after his move from Ajax.
He told Betfair: "The Premier League is a different league, and players will be shocked when they see the defenders and how much stronger and faster they are. We have to give Antony time, but he's a good signing.
"I hope that Ten Hag won't rely on the players he's coached in the past too much because it's a different league, but I think what he is looking for right now is trust.
"He wants to trust those players, and know that they are going to die for him. I think this is the right direction, but he has to make sure that if results go bad he can change things."
On Lisandro Martinez, Evra continued: "Lisandro Martinez is a pit bull, he's going to give his life and that's what we need.
"South Americans play with passion and they give everything, it's like they are going to war.
"I remember when Martinez signed for United, he said every game is important, and people started to judge him too soon.
"I'm not surprised with what he is doing and how well he is performing. "
