Pierre-Emerick Aubameyang has been accused of not trying for Borussia Dortmund as he tried to force a move to Arsenal.
The Gabon hitman completed a £57.5million move from the Bundesliga giants to The Emirates in January after a month-long chase by the Gunners.
Aubameyang was suspended by Dortmund last season for breaking rules when he made an unsanctioned trip to Milan and was also handed a separate internal ban by the club for missing a team meeting in January.
And Dortmund CEO Hans-Joachim Watzke has hit out at the player for downing tools to force his way out of the club, similar to what winger Ousmane Dembele did to get his big-money switch to Barcelona last summer.
Aubameyang did apologise for his behaviour in an Instagram post, where he wrote: “First of all sorry for everything that happened over the last month.”
Watzke, however, has insisted that situation will no longer be tolerated by the club.

He told FAZ: “On Thursday, I laid it on the line for the squad — the next player who does something like that will fail miserably.
“He’ll run into major problems. The next player who tries to put us under pressure by withholding performances or even going on strike will not get a pass and will instead sit in the stands.
“They are all aware of it. This is now a public statement. Following Dembele and Aubameyang, there is now an overriding interest for the club — we need to get a better structure into our squad again.
“Aubameyang committed himself to us for this season, especially as a reaction to Dembele’s transfer.
“But he also had the notion that we owed to him because in 2016 he opted for us and decided against very lucrative offers amid the exits of [Mats] Hummels, [Ilkay] Gundogan and [Henrikh] Mkhitaryan.”
Watzke also revealed the reason why he allowed Aubameyang to join Arsenal.
He added: “Because we had the impression there will be no new start for him in the Ruckrunde [second half of the season]. Not with the fans, not with the team. Too much had been damaged through his behaviour.”
