Marcus Rashford was among the first players to clash directly with Ruben Amorim upon the Portuguese coach's arrival at Manchester United.
Just weeks later, the England international was loaned to Aston Villa, where his performance didn't quite live up to the potential everyone recognized in him.
Nevertheless, Barcelona capitalized on Amorim's continued disinterest in the winger, securing him on loan with a €30 million option to buy. The newly crowned Spanish champions are now looking to negotiate that fee down to keep the player permanently.
However, some argue that €30 million is a steal for a player of his caliber. Ronald Koeman is one such figure who believes the Catalan giants must retain the Englishman at all costs.
"If Barcelona lets Rashford return to Man. Utd after this loan, they will regret it forever. Because €30 million in today's market, for a player with these characteristics, numbers, and experience… it's an absolute bargain," he declared, as quoted by As.
The former defender, a Barcelona playing legend who also managed the club – and Benfica, for instance – cited the English winger's performance against Real Madrid as a prime example.
"Rashford causes problems for opponents. Real Madrid looked terrified every time he turned and accelerated. He completely destroyed them in transitions. Speed, aggression, verticality, confidence… Real Madrid couldn't stop him," he praised, before concluding.
"He scored from a free-kick in El Clásico, creates numerical superiority, presses, plays with his back to goal, and yet there are still people at the club who hesitate to pay €30 million for him? That seems crazy to me."
With 47 appearances this season, the English winger has tallied 14 goals and 12 assists since arriving in Catalonia at the start of the season.
