 One of the key decisions Robson made during his brief tenure at Barcelona was the US$19.5 million signing of Ronaldo, who was influential in a season when Barcelona won the Copa del Rey, Supercopa de España and European Cup Winners' Cup.Robson himself was voted European Manager of the Year for 1996–97, while Ronaldo stated, "as a trainer without doubt [Robson] is one of the greatest in the world".The 1997–98 season saw Robson moved "upstairs" to the general manager position, with Louis van Gaal taking over as manager, but Robson stayed in this position for only one season before returning to manage PSV on a short-term deal for the 1998–99 season.
