Manchester United believe interest in Borussia Dortmund's Jadon Sancho and Chelsea's Callum Hudson-Odoi will have to be shelved with their respective clubs maintaining they do not wish to sell.
Ole Gunnar Solskjaer wants a right back, two midfielders and a right winger for his summer rebuild.
England internationals Sancho and Hudson-Odoi have been discussed but there is a growing air of realism around the United camp that both will be extremely difficult to prise away this summer.
Dortmund have already stated they are planning for Sancho to stay with sporting director Michael Zorc underlining 'it will be very difficult even for the biggest of clubs' to buy the former Manchester City winger, particularly with Christian Pulisic leaving for Chelsea this summer.
City negotiated a matching rights clause in Sancho's contract which enables them to offer the same amount as rival suitors, should Dortmund agree to sell, but the German club have proven stubborn in the past once they make such a declaration.
They know clubs may be willing to offer up to £100m for the 19-year-old but point to the fact he is tied to a contract until 2022 and could improve again by playing more regularly next season.
Chelsea have less security over Hudson-Odoi as he has just one year remaining on contract but they still plan to reassure him he will feature more regularly and are reluctant to allow him to join Premier League rivals.
They also point to the fact that other suitors Bayern Munich, while offering a lucrative contract, do not have a track record for giving teenagers greater game time.
The risk for Chelsea is he could go abroad for relatively low compensation next year while United could be asked to pay up to £20m at a tribunal here.
Chelsea's appeal against their transfer ban will be heard next Thursday, April 11, and they are exploring whether taking their fight to the Court of Arbitration will still allow them time to conduct transfer business.
Real Madrid are expected to improve their offer for Eden Hazard while Barcelona, Paris St Germain and Chinese clubs remain interested in Willian. As such, losing the much younger Hudson-Odoi is not in their interests.
United want Crystal Palace right-back Aaron Wan-Bissaka as a replacement for Antonio Valencia, who has interest from West Ham and MLS clubs, while United have also been offered Atletico Madrid midfielder Thomas Partey among others.
Meanwhile, United players' pre-match rest was disrupted when hotel fire alarms went off on Tuesday.
The United squad was staying at the four star Mount Hotel Country Manor, Tettenhall, prior to their Premier League game with Wolves.
Players checked in at 9pm on Monday evening for their overnight stay but as they prepared themselves for the match at Molineux with an afternoon sleep on Tuesday, their peace was disrupted by the hotel fire alarms going off twice.
Striker Marcus Rashford was sent home from the hotel yesterday afternoon suffering from a heavy cold as well as needing further treatment for his ankle injuries.
Defeat at Molineux left the United dressing room in sombre mood as they contemplate missing out on a top four place.
