The club has severe financial issues and have had to let go of Lionel Messi this summer as their wage bill is way above the La Liga salary cap.Koeman reportedly met with the Barcelona board and sounded out the idea of signing a striker and a midfielder before the end of the transfer window. The club, however, is currently focusing on offloading players to trim their wage bill and cannot dedicate their resources towards signing players.Koeman asked Barcelona to sign a new midfielder & forward following Aguero's injury & Messi's departure, but he has been told that new signings are very unlikely. The arrival of a new forward could only happen if Braithwaite is sold for a good price. #FCB [@tjuanmarti] pic.twitter.com/kS2CDzxCYU— Football Talk (@Football_TaIk) August 12, 2021Benfica keen on signing Samuel UmtitiFC Barcelona v Gimnastic de Tarragona - Friendly MatchBarcelona are desperate to offload quite a few of their first-team players this summer.
