Liverpool manager Jurgen Klopp turned down the opportunity to sign a striker whilst at Borussia Dortmund because of the way the player celebrated scoring a goal, Dortmund marketing director Carsten Cramer told the Mirror.
Klopp became known for his occasionally unorthodox methods at the German club and this has continued to some extent in England, with the German receiving a mixed reaction from fans and media for leading his players to thank the Anfield fans after his side rescued a late draw against West Brom in December.
It seems that the 48-year-old's unusual style also has an impact on his transfer activity, with his former colleague revealing how Klopp changed his mind on a target a few years ago after being unimpressed with what he saw from the player after he found the net.
Cramer told the Mirror: "There is a story Jurgen told me about a striker he was interested in. He watched him in several videos and said: 'This is a striker I want to sign.'
"Then he saw him playing and he scored a goal. He was watching how he was celebrating his goal and said: 'This is not a guy for Dortmund. He is celebrating for himself and not the club.'
"All the players know the club is the most important thing. I'm very sure that the brand philosophy was important when we hired someone like Jurgen Klopp."
One of the key messages sent by Klopp on a consistent basis at both Dortmund and now at Liverpool is one of team unity and everyone pulling in the same direction.
The manager's playing style is based heavily on his players working as one unit in applying pressure to opposing sides when trying to win possession back, and in combining well when on the ball themselves.
As such, it is perhaps unsurprising that any sign of an ego or lack of teamwork is a big turn-off for Klopp in the transfer market, with any potential new recruits having to be able to fit the German's mould.
Liverpool fans will get to see Klopp in action in a summer transfer window for the very first time after the end of the current season.
