The coach fears that the Blaugrana will lack firepower if the six-time Ballon d'Or winner departs the club on a free transfer in the summer
Barcelona head coach Ronald Koeman has said it is “impossible” for Barcelona to play without Lionel Messi after what might have been the star’s final match at Camp Nou.
Out of contract at the end of the season, uncertainty still hangs over Messi’s future, and more so after Barca’s frustrating conclusion to the season.
Although the Copa de Rey was claimed, Barca can finish at best third in La Liga, having won only one of their last five matches, including a 2-1 defeat to Celta Vigo on Sunday.
