Manchester United worry Barcelona as they prepare to go all out for Messi

Manchester United have major plans for the upcoming summer as they prepare to seriously contend for the 2020/21 Premier League title after Liverpool have dominated this season in the English top-flight divisions. The Red Devils have several players on their list for the summer and some of them are surprisingly from Barcelona as well.
The English side was first heavily linked with Antoine Griezmann of Atletico Madrid in the summer of 2019 before the Catalans trigged his 120 million euro clause. With Griezmann out of the picture, United considered Ansu Fati who has been phenomenal for the Blaugrana this season when given the opportunity. However, the board at Barca was not willing to accept any offer for their teenage prodigy apart from meeting the 150 million euro release clause.
Manchester United had no other option but to look at other options in the market and have recently been heavily linked with Jadon Sancho of Borussia Dortmund who would cost approximately 100 million euros or more.
