Manchester United attempted to bypass agent Mino Raiola in their efforts to sign Erling Haaland from Red Bull Salzburg.

The 19-year-old was a priority target for manager Ole Gunnar Solskjaer but United lost the race to sign one of the most sought-after teenagers to Borussia Dortmund.

United claim they pulled out of the deal to land Haaland after refusing to meet Raiola’s demands. And Sportsmail understands United tried to strike a deal with the forward’s father, former Leeds midfielder Alf Inge Haaland, who also represents his son.

Erling Haaland looked happy after arriving for his first day at Borussia Dortmund on Friday

But United’s attempt failed and the Norway international signed for Dortmund after the German club met the £18million buyout clause in his contract.

Dortmund have also agreed to give Raiola and Haaland Snr a significant share of the future sales value, meaning the agent will control Haaland’s next transfer — something United were not prepared to sanction.

Raiola has played a central role in some of the club’s most expensive transfers in recent years. He helped bring Paul Pogba to United from Juventus for a then world record £89million fee.

He negotiated Zlatan Ibrahimovic and Henrikh Mkhitaryan’s moves to Old Trafford and also brokered Romelu Lukaku’s £75m switch to United from Everton in the summer of 2017.

But the 52-year-old has angered United in recent months, particularly in relation to Pogba’s future at the club.

‘Pogba’s problem is Manchester United,’ Raiola said earlier this week. ‘It’s a club out of touch with reality, without a sporting project. I wouldn’t take anyone there. They would even ruin Maradona, Pele and Maldini.’
