The budding American superstar showed his potential by weighing in with goals and assists while Blue secured a place in the Champions League.
However, the 21-year-old might have moved to United if the Reds had secured his services when ex-club scout Jorge Alvial had recommended him.
“When I first hired one of the people I recommended right away was Pulisic because I knew him and his past,” he told MEN.
“I knew how well it was developing in Dortmund and would continue to grow and become a superstar because it was going very well.
“I have always believed in him, we have always had close contacts with his father and I called him to say that I recommended him to Manchester United.
“So, it has been many times that I have recommended it, but at the same time because I was only doing North America, it was not my region because it played in Germany.”
Pulisic entered into an agreement at Stamford Bridge with a transfer worth £ 54 million.
Alvial added: “We all had a list and I had it together before [Bayern Munich’s] Alphonso [Davies].
“I strongly advised them to sign it, and I also know that the German scout was very fond of him, he also liked it very much. It was not a case of” look at this guy “, it was” sign it “. ‘
“When I recommend a player, he is usually an example of a player that I think has enormous potential.”
