Arsenal are stepping up their pursuit of Pierre-Emerick Aubameyang, with the club's transfer negotiators having been in Germany for their first round of talks with Borussia Dortmund.
Ivan Gazidis, the club's chief executive, new contracts expert Huss Fahmy and Sven Mislintat, the head of recruitment who joined from Dortmund, touched down on Sunday afternoon in a bid to move talks forward on a deal for Aubameyang.
As reported by Goal earlier on Sunday, Alexis Sanchez is on the verge of completing his move to Manchester United having arrived for a medical with the club, with Henrikh Mkhitaryan heading in the opposite direction.
Gunners boss Arsene Wenger wants to add world-class attacking talent to his side and sees Aubameyang, a former team-mate of Mkhitaryan at Dortmund, as the perfect forward to complement the likes of Mesut Ozil and Alexandre Lacazette.
Arsenal lodged their first formal offer for the Gabon international on Saturday, with reports suggesting that Dortmund value Aubameyang at £53 million, and it's understood the German side are looking at Olivier Giroud being used as a potential makeweight in the deal.
The German club's CEO Hanz-Joachim Watzke told Ruhr Nachrichten: "I can confirm that there has been a first request from Arsenal for Pierre-Emerick Aubameyang and we are not commenting on the sums that have been called from England since noon today [Saturday]."
Discussions between the Gunners and Dortmund on Sunday lasted several hours with Mislintat confirming to local German media that nothing had been finalised as of yet.
Photos from Germany also showed Aubameyang's sports car parked at the same Dortmund Airport terminal. Goal revealed last week that the striker, who has scored 21 goals in 23 appearances this season, has already agreed personal terms with the club.
Aubameyang has endured a frustrating season with Dortmund, with disciplinary issues having previously seen him internally suspended and dropped from the first-team squad.
Despite those conflicts, he has still raced to 13 goals in the Bundesliga this season, a tally bettered only by Bayern Munich striker Robert Lewandowski.
