Borussia Dortmund are increasingly confident of keeping star striker Serhou Guirassy after a host of European giants failed to activate his cut-price release clause. The Guinea international, who was one of the most prolific scorers in the Bundesliga last term, saw his exit option expire at midnight on Wednesday.

Arsenal have reportedly reached a total agreement with Club Brugge for the transfer of Christos Tzolis. The Gunners are set to pay a fee in the region of £34 million to bring the Greece international back to the Premier League.

Arsenal and France defender William Saliba was forced off the pitch during his nation's World Cup semi-final match against Spain due to a back injury. France ultimately suffered a 2-0 defeat, ending their campaign. Saliba has been managing the issue for several months, and his sudden withdrawal has sparked fears that he may now require surgery ahead of the new season.

Arsenal have confirmed they have reached an agreement with Turkish giants Besiktas for the permanent transfer of Leandro Trossard. The Belgium international is now travelling to Istanbul to undergo a medical examination and finalise personal terms on a reported three-year contract, bringing an end to his successful three-and-a-half-year spell at the Emirates Stadium.
