Liverpool have had an incredibly busy January in the transfer market and we’re not even two weeks in yet.

The Reds had already wrapped up a deal for Virgil van Dijk before the transfer window had even opened but were soon selling their star man, Philippe Coutinho, to Barcelona.

What they do with that £142 million is unknown but there are calls on Jurgen Klopp to spend that money immediately.

The likes of Thomas Lemar and Riyad Mahrez have been linked but it’s looking increasingly likely that Liverpool will wait until the summer to make a move for either of them.

And another player Liverpool might wait until the summer to sign is Borussia Dortmund’s Christian Pulisic.

Liverpool were linked with the American last summer but Klopp was unable to strike a deal with his former club. However, he’s kept close tabs on the 19-year-old and could reignite his interest in six months time.

However, Liverpool have a problem.

WHAT MAN UTD HAVE PLANNED FOR PULISIC

According to the Independent, “Manchester United are willing to strongly challenge” them if they make any move for Pulisic.

The report states that, although United see the winger as an excellent footballer, they also see the youngster making millions for the club on the commercial side of things.

They write: “While the 19-year-old attacker is obviously seen as an excellent football signing in his own right and fill a hole for Jose Mourinho’s side, an extra angle is the view that talent could well make him the USA’s first megastar in the sport, with all of the commercial value that will bring. United’s marketing side would see him as another Paul Pogba in that regard, as do many other suitors.”

The report goes on to state that Liverpool are expected to make a bid for Pulisic in the summer with Klopp a “huge admirer” of his.

But there is no guarantees that he will want to leave Dortmund in six months time having been given opportunities in the first-team this season. He’s played 23 times in all competitions, scoring four goals, and has previously talked about pleased he is with his development.

“I am playing every week in the Bundesliga, in the Champions League, against top teams,” he says.

“When you do that every week, you are going to improve. When you play against the best players, you’re going to grow. I’m learning a lot: tactically, technically, gaining strength.”

But if Man Utd and Liverpool come calling in the summer, Pulisic might have a tough decision on his hands.
