Sir Jim Ratcliffe’s £1.25bn investment in Man United is set to be confirmed the week after next… as British billionaire is made to wait to land 25% stake at Old Trafford

Sir Jim Ratcliffe's 25 percent stake in Manchester United is not expected to be announced until next week.

Mailsport understands officials had hoped to broadcast the Ineos billionaire's arrival ahead of Bayern Munich's match at Old Trafford on Tuesday.

However, sources in the US have revealed that 'legal structural' matters have pushed back the date.

There are not believed to be any obstacles or concerns, but the delay could prove frustrating for supporters who see the arrival of the United-supporting local businessman as the beginning of the end for the Glazer family, who will retain a majority stake.

If matters remain unresolved, the upcoming Christmas holidays could push the announcement to the new year, although those involved hope this is not the case.

Ratcliffe is said to have paid almost £1.3 billion for a quarter share in United.

The British billionaire will buy 25 percent of the A shares listed on the New York Stock Exchange, as well as 25 percent of the Glazers' B shares, which have greater voting rights. He will pump an extra £245 million into the club to upgrade Old Trafford and Carrington.

Once announced, approval is expected to take around six to eight weeks, meaning the new group may not arrive in time for the January transfer window.

He beat off competition from Qatar's Sheikh Jassim bin Hamad al Thani, who withdrew from a two-horse race for the Premier League giants in October.

More than a year has now passed since the Glazers said they were looking for investment and were open to an outright sale.
