Christian Pulisic is struggling for game time at Chelsea for the past two seasons.
The USMNT winger has been the subject of interest from Man United since the past few days.
He has struggled to impress Tuchel and only started 10 Premier League games last season for the Blues.
The 23-year-old is contemplating his future since the arrival of Raheem Sterling this summer which would further derail his chances in the first-team.
Newcastle United are also looking for some attacking options before the deadline day and has been urged to make a move for the talented winger.
Alex McLeish said: “Is he similar to Almiron? He’s not so much a centre-forward, more of a number 10 or he comes in from the wide areas.
“These are the types of players Newcastle will be looking at. Pulisic has not made the impact you thought he might when Klopp had him at Dortmund. Klopp thought he had everything.
“He hasn’t made a massive impact with Chelsea, even though when he does come on you think ‘wow. this guy catches the eye’. Maybe there is less pressure in going to a club like Newcastle, it might help him.”
