Borussia Dortmund Reportedly Ready to Sell Pierre-Emerick Aubameyang

Borussia Dortmund are reportedly ready to cash in on star forward Pierre-Emerick Aubameyang after his turbulent beginning to the season.

According to Bild (h/t Will Griffee of MailOnline), the Gabon striker is edging closer to the Westfalenstadion exit door, with Chelsea and Liverpool said to be two clubs interested in signing him.

The club suspended Aubameyang for disciplinary reasons earlier in the season, and he was sent off against rivals Schalke 04  on Saturday with his team 4-2 ahead. Having been four goals to the good, Dortmund ended up drawing 4-4.

As Griffee noted, key figures at Dortmund didn't hold back when they were asked about Aubameyang's conduct in the Revierderby.

Goalkeeper Roman Weidenfeller said the striker had "done a stupid thing," while manager Peter Bosz went as far as saying Aubameyang had "ruined everything" by getting sent off.

Saturday's game was eventful for the forward, who netted the opening goal.

Aubameyang has established himself as one of the deadliest goalscorers in football since arriving at Dortmund in 2013.

While this campaign has been blemished by some disciplinary issues, the Gabon international has still been prolific. His goal on Saturday was his 11th in the Bundesliga from 12 appearances this term, and he struck 56 times in the German top flight over the previous two campaigns.

Evidently, if he were to move on, his departure would leave a massive void at the point of the Dortmund attack, where Aubameyang offers deadly finishing and blistering pace.

With that in mind, there would be a number of clubs ready to snap him up if Dortmund were ready to cash in. As previously mentioned, Premier League sides have long been linked with signing Aubameyang, who recently told RMC Sport he was "disappointed" a move to Real Madrid failed to go through in the summer (h/t Jamie Wright of MailOnline).

Dortmund have sold many key players in recent years and have done well finding replacements. Aubameyang himself assumed the centre-forward berth after Robert Lewandowski's departure to Bayern Munich in 2014.

Even so, there aren't many strikers as devastating as the former Saint-Etienne sharpshooter when he's in full flight. It means Dortmund have a massive decision to make ahead of the January transfer window or at the end of the campaign.
