According to former Premier League striker Jan Aage Fjortoft, Liverpool are now the favourites to sign Jadon Sancho from Borussia Dortmund.

What's the story?

The 19-year-old, who signed for the Bundesliga club in 2017, is said to be looking to depart as soon as January as per the 52-year-old's sources in Germany.

On top of that, he added that the former Manchester City player does not have a clause in his contract, and that BVB are looking for £130m for his services.

Attitude problem

There is no doubting that the youngster is an extremely promising talent. Last term, he picked up 12 goals and provided 17 assists in the league, whilst he also featured in the Bundesliga Team of the Year. This term, he has has five goals and seven assists already, whilst he managed to pick up 11 England caps as well despite his tender age.

However, there clearly seems to be an issue with the winger's attitude and punctuality. Against Barcelona last week in the Camp Nou, he was dropped to the bench. Afterwards, it was revealed that it was because he was late to a pre-match team meeting.

If it was a one-off, it could be brushed under the carpet and would be forgotten about. That is not the case, though. It is actually the second the time this season that such a situation has occurred following Sancho's tardiness after October's international break. And it has happened in previous years, as well, with him being demoted to Dortmund's U23 squad in the 2017/18 season after, once again, being late.

This, of course, does not mean that Jurgen Klopp should drop all interest in the teenager - as we explained a few weeks ago, his ability on the pitch illustrates why he would be a fantastic signing, and perhaps an even better fit than Kylian Mbappe - but it is certainly something for him and Liverpool's hierarchy to consider. Sancho is not the finished article - not only in regards to his ability, but also his mentality - and the former Mainz 05 boss will need to work on him psychologically as well as on the training field.

He has had it pretty much all his own way in Germany. The fact that he is said to be unsettled due to the events of this campaign - which are of his own making - shows that as soon as a couple of issues occur, he may be looking to move on, rather than stick it out and correct the error of his ways. As such, the European champions should at least be aware they would have a lot of work to do with the precocious talent.

Meanwhile, Karl-Heinz Rummenigge says one Liverpool star was previously a target for Bayern Munich.
