Reports say Arsenal have agreed terms to sell forward Leandro Trossard to Besiktas ahead of the summer transfer window. Multiple outlets cite The Athletic as the source, indicating that Besiktas are set to pay a fee in the region of £17.1 million, with some reports describing the deal as worth €20 million overall. One report specifies the structure as €18 million fixed plus €2 million in realistic add-ons. Trossard, a Belgium international, has less than 12 months remaining on his contract with Arsenal, which is presented as a key factor in the decision to move him on. The reporting also frames the transfer as part of a broader summer overhaul at Arsenal, with the 31-year-old now edging closer to leaving the Emirates. The sources do not provide confirmation of the final medical or signing, but they consistently state that an agreement between the clubs is in place and that the transfer is expected to be completed once remaining steps are finalized.
