Brenden Aaronson has not been directly involved a single Leeds United goal since returning from the World Cup with the United States.
The 22-year-old, who was signed by Jesse Marsch from Red Bull Salzburg back in the summer, took just three Premier League games to open his goal scoring account in a 3-0 win over Chelsea in August.
However, Aaronson has registered just two assists since, with both of them coming before he jetted off to Qatar for the World Cup in November.
Despite his lack of form, Marsch started him in 19 of his 20 league games at the helm this term, and only dropped him in his final game, which Leeds lost 1-0 at Nottingham Forest.

Aaronson posed a threat in the final third after coming off the bench in Leeds' 2-0 defeat at Fulham in the FA Cup fifth round on Tuesday, but ex-Leeds defender Newsome believes his lack of productivity in the final third is a real concern.
“I thought he made a real impact when he came on. He should have scored a goal and maybe created another one, but over the past couple of months, since the World Cup, he has not really produced anything," Newsome said on BBC Radio Leeds.
“His stats – assists and goals – they are the departments we are lacking in.”
