A 34th minute finish by Marko Arnautovic secured victory for the Irons against the League One opposition at Adam's Park, and the Chilean boss believes the Wycombe tie was another good test for his side.
“My words are exactly the same as they were when we lost against Winterthur in Switzerland," Pellegrini told West Ham TV. “We are not preparing a starting XI and we don't make substitutes to win the game.
“The pre-season games are useful for what we in need in this moment, which is to recover our physical shape and to try to return to our best, technically. And to see different players, young players, so I think today was the same as the first game. It was a useful game.
“We worked very hard for eleven days in Switzerland and, for some of those days, we worked three times a day. We have a very good answer to that work. It's not easy, when you've had forty days of holiday, to return to your competitive mind and your best physical shape.
“But our players are working hard and we have time to get to our best for the beginning of the Premier League season."
