Brentford boss Uwe Rosler praised Mike Grella for scoring four goals as the Bees thrashed Bournemouth 6-0 in the Johnstone's Paint Trophy.
It was only the American's second start since joining from Swindon in the summer but his manager feels he is benefiting from working hard in training.
Rosler told the Hounslow Chronicle: "When Mike came to us, he was struggling with what we wanted from our strikers. It took him longer than expected and it took a lot of talks on the training ground.
"Mike's still doing his tricks, but he's now making runs into the right areas, bringing others into the game, playing it shorter and releasing the ball quickly.
"He still wants the ball to his feet, but he knows he has to make the runs and make the space, and he's more dynamic now.
"But the most important thing is for a striker to score goals, so I am very happy with him. However, there was also great service to him, it was a great team performance."
