Ole Gunnar Solskjaer heaped the praise for Manchester United's new signings, particularly towards young Facundo Pellistri.
The 18-year-old Uruguayan joined the club from Penarol for a fee of around £9 million on transfer deadline day this month.
Solskjaer has been impressed by the youngster in his first few days in training as a Manchester United player.
The Uruguayan has been training with those first-team players that have not been on international duty in the past few days.
Along with Pellistri, United also signed Alex Telles, Edinson Cavani as well as Amad Dialloon transfer deadline day, with the latter arriving at the club in January.
Solskjaer has identified Pellistri and Diallo as players for the future given their youth, but he is liking what he is seeing in Pellistri so far.
Speaking during his pre-match press conference, Solskjaer said that "Facundo, he's been in training with us for two days. Very exciting, young, enthusiastic player with some attributes that we don't have".
He added that "Of course, he's one maybe more for the future, maybe not for just now because he's still 18."
Solskjaer also stated that it might be a while before United fans are able to see either Telles or Cavani, with Telles only recently arriving from Brazil, whilst Cavani is in quarantine.
Speaking on the three signings that arrived on deadline day, he said "All three of them have got something different to what we have. And they'll definitely come in and help us."
Apart from new signings, the United manager also hinted at out-of-form Harry Maguire's possible absence against Newcastle, claiming that he picked up a knock against Denmark before being sent-off.
