Liverpool boss Jurgen Klopp is full of praise for Arsenal striker Pierre-Emerick Aubameyang.

Klopp signed the Arsenal striker from St Etienne in 2013 when he was Borussia Dortmund boss.

“It is four years since I worked with him," said Klopp.

“Everything knows everything about everybody, that is how it is and there are no surprises.

“Auba has actually no real weaknesses apart from his fashion style."

Klopp could not have an impact on Aubameyang's style off the pitch but he did help him develop from a winger at St Etienne into a forward who would go on to score 98 goals for Dortmund in 144 games.

“He played as a winger at St Etienne at that time, we needed a No. 9 because Robert Lewandowski was leaving us," said Klopp.

“We thought long about it, then he came in and played on the wing. Later on we realised he is a really good central striker, a No. 9 as well.

“It was not immediate like this, he developed incredibly and became a goal machine and I have to say his finishing is incredible. Combine that with the speed and it is really interesting."
