Marcus Rashford said his choice to join Barcelona was "easy"

"He is unbelievable. He has more potential he can show us."

That was Hansi Flick's verdict on Marcus Rashford in September, before the forward's return to England for his first Champions League appearance with Barcelona.

The head coach's confidence seemed to inspire Rashford. He scored his first two goals for the Catalan giants and led them to a 2-1 victory against Newcastle at St James' Park.

It was the breakthrough Rashford had been waiting for since he joined Barcelona in July - a loan move from Manchester United that raised several questions.
