Liverpool have a fight on their hands to land the signature of highly-rated Dortmund midfielder Christian Pulisic.

The Daily Mail have claimed that the Reds are looking to add another attacking option with Philippe Coutinho’s injury causing further problems to the forward line.

Jurgen Klopp is reportedly keen to add 18-year-old USA international Pulisic to his squad in January, but the German club have issued a ‘hands off’ warning to the high flying Premier League outfit.

According to German newspaper Bild, Dortmund sporting director Michael Zorc has insisted that £25million-rated Pulisic is not for sale, and that Liverpool should not even bother making a formal approach.

“It’s not worth the effort for Liverpool,” he said.

Pulisic has flourished under Thomas Tuchel this season, contributing two goals and five assists from 14 appearances in all competitions.

Despite only making his breakthrough least season, the American is now considered a key part of a first-team squad the contains some of Europe’s top attacking talent – including Germany’s 2014 World Cup hero Mario Gotze, Shinji Kagawa, Marco Reus, Andre Schurrle and African Footballer of the Year nominee, Pierre-Emerick Aubameyang.

Liverpool already have a potent attacking-force of their own, and are the Premier League’s highest goalscorers this term with 32.

Jurgen Klopp still has work to do defensively, but he’s turned the Reds into a free-scoring attacking unit that is great to watch.

Attacking trio Roberto Firmino, Philippe Coutinho, and Sadio Mane – who have six goals apiece – were all on the scoresheet as Liverpool thumped Watford 6-1 in the Premier League on November 6.

But Klopp is still keen to add further fuel to the fire in attack this month, as Liverpool prepare to fight their title rivals for the 2016-17 Premier League crown – and Pulisic is his number one target.

In other Liverpool news, the club have been handed a major boost as Adam Lallana could return to action in time for their game against Bournemouth.
