FOOTBALL: Manchester United's deal for Victor Lindelof delayed over outstanding sell-on clause - but it's still on

A negotiation over a sell-on clause is delaying Victor Lindelof 's protracted move to Manchester United.

Despite suggestions otherwise it is understood United's move for £38million-rated Lindelof is still on.

But a dispute over an outstanding payment to the Swede's former club Vasteras is holding matters up.

Should Benfica fail to get the 20 per cent fee reduced (around €250,000), they have informed United they will have to make up the difference as part of Lindelof's transfer package, report the Manchester Evening News.

Vasteras, whose last home match was attended by 385 spectators, could pocket £7.6million if Lindelof leaves for £38m and Benfica have omitted the Sweden international from their matchday squads in their last two games.

Vasteras were entitled to an additional payment after Lindelof made 10 senior starts in the Primeira Liga and Champions League and the Swedish side has submitted a formal complaint to Fifa’s players’ status committee over Benfica's conduct.

It emerged last week United had cooled their interest in Lindelof, citing the impressive form of central defensive pairing Phil Jones and Marcos Rojo, who have started nine of the last 10 unbeaten Premier League matches.

United scouted Lindelof three weeks before the transfer window opened and Benfica coach Rui Vitoria admitted last month the club was prepared for Lindelof's possible departure in the new year.

"Sometimes players have to leave because their careers, their age, the way they are playing and developing means there will be clubs interested who can give them a different life and take them on a different path," he said.

"If this happens, we have solutions. We have a B team packed with great players and in the short term some of them will be playing for Benfica's first-team."

Over the last six years, Benfica have sold 13 of their most sought-after players for a total of £270m and last year United missed out on signing Renato Sanches because of their failure to appoint Jose Mourinho sooner.

Lindelof has already played 22 times for club and country this season and is just the latest Benfica talent to interest United.

The club monitored Javi Garcia, Ezequiel Garay, Nico Gaitan and, most recently, Sanches. Sanches' agent Jorge Mendes convinced United executive vice-chairman Ed Woodward to scout the teenager in January last year and he was then regularly watched by United but joined Bayern in May.

United have never signed a player from Benfica.
