United signed Cavani on a free transfer, Brazilian left back Alex Telles from Porto, Uruguayan 18-year-old winger Facundo Pellistri and reached an agreement to sign Atalanta’s teenage winger Amad Diallo.
United’s 6-1 thrashing at home by Tottenham Hotspur on Sunday has increased the pressure on chief executive Ed Woodward to give manager Ole Gunnar Solskjaer some new options. Attacking full back Telles and experienced former PSG forward Cavani now join Netherlands midfielder Donny van de Beek, who moved to United from Ajax last month.
Cavani was a free agent after leaving Paris St Germain and said he was looking forward to the challenge at Old Trafford.
“I look forward to continuing to write my little story inside the book of football” he said.
