Barcelona have a £30 million option to buy Rashford in their loan deal, although his wages may be a sticking point if they decide to activate it. The England international will need to prove himself before the financially troubled club makes a decision.
So, how is Rashford getting on at Barcelona?
Adapting to a new system
Rashford was brought in to provide cover for Barcelona's attacking unit, which scored 94 goals and provided 46 assists last season. With Raphinha and Lamine Yamal struggling, Rashford has had to adapt quickly to the team's system.
The Englishman is averaging a goal or assist every 88 minutes so far this season, assisting 4 and scoring 3 in just 616 minutes. Despite Barcelona's underwhelming start to the season, Rashford has been a bright spot.
Flick's system demands 120% from his players, with intense pressing and tracking back expected from the forward line. Rashford has totally embraced the system, winning possession back in the final third four times already.
Rashford is playing similarly to how he did when he first came through at Manchester United, using his pace to catch opposition defenders out on the counter. He excels in one-on-one situations and has already had 50 touches in the opposition box.
Fitting in with his new teammates
Rashford has made a good impression on his new teammates and is already fostering relationships with those who speak English. Jules Kounde has praised Rashford's integration, saying he's "really enjoying himself" and feeling more comfortable every day.
Rashford has even earned a sweet new nickname from his teammates, who call him "sweetie" when they're having fun together. He's also learning Spanish and appreciates the help his teammates are giving him.
What does the future hold?
England boss Thomas Tuchel is a big fan of Rashford, recalling him for his first squad while he was struggling at Aston Villa. Rashford has featured in every squad since then and could be in line for a place in the World Cup squad next year.
Verdict
It's early days, but Rashford is proving a lot of people wrong. He's shown consistency and adaptability, and his wages will be a major factor in whether Barcelona can afford to sign him permanently.
