Juventus forward Paulo Dybala is reportedly stalling on a move to Manchester United as he is unsure about joining a club not currently competing in the Champions League.
United's sixth-place finish in last season's Premier League means that they will be without top-level European football during the 2019-20 campaign.
According to The Mirror, the fact that the Red Devils will not be present in the European Cup means that Dybala must be convinced to join the 20-time English champions.
The Argentina international has reportedly been offered to Ole Gunnar Solskjaer's side in a swap for Romelu Lukaku.
The 25-year-old, who scored 10 times in 42 appearances for Juve last term, is also said to be looking for wages of around £350,000 a week at Old Trafford.
The Red Devils are therefore seemingly facing an anxious wait as they look to complete a deal for the South American before the window closes on August 8.
