Former Chelsea striker Pierre-Emerick Aubameyang has taken a dig at the Blues following Hakim Ziyech's loan move to Galatasaray.
The Turkish club have paid a loan fee of £3million for Ziyech, and will pay a further £2.4 million if they wish to make the move permanent next summer.
He was unveiled in the stands at RAMS Park after Galatasaray beat Trabzonspor 2-0 and led a chant from supporters.
The move comer after numerous failed attempts from Ziyech to leave Chelsea, a club where he failed to establish himself in the first team and scored just 14 goals in three years.
In January, a last-gasp loan move to Paris Saint-Germain fell through on deadline day after Chelsea failed complete the necessary paperwork to seal the deal with the Ligue 1 champions.
Earlier in the summer window, a bid to book a move to the Saudi Pro League fell through after the winger failed his medical following the discovery of a knee problem.
It was the failed attempts to leave Stamford Bridge that Aubameyang poked fun at, posting a message on Instagram that read 'All the best my bro Free Hakim' above an image of his former teammate.
The 34-year-old is another player who has left Chelsea this summer after one of the of least successful spells in his career.
Aubameyang spent much of his one season on West London on the bench, and scored just one league goal in 15 appearances.
He joined Marseille in July, and has started the season with two goals in his four appearances for the French side.
Chelsea are yet to sign a proven number nine to replace Aubameyang, although new forward Nicolas Jackson did look promising in their first game of the season, a 1-1 draw with Liverpool.
Mauricio Pochettino's side will next be in action on Sunday when they face West Ham at the London Stadium.
