Cape Town - Manchester United striker Romelu Lukaku has reportedly failed to report for training at the club's Carrington base and is instead training with Anderlecht in Belgium.
The Belgium star does not feature in Ole Gunnar Solskjaer's long-term plans for the Red Devils and is available for sale.
But United are looking for a fee in excess of the £75 million they paid Everton two years ago, which has so far priced out Inter Milan and Juventus.
In the meantime, Lukaku has yet to feature in pre-season, despite travelling with the club on the tour to Australia and the Far East.
He was left out of the squad which faced AC Milan in Cardiff on Saturday and on Monday, he was pictured training with his former club Anderlecht.
United refused to say whether he had been given permission to return to Belgium, revealing only that Solskjaer's first-team squad had the day off.
But Lukaku was reportedly due to report back to Carrington on Tuesday morning, but instead, he has again been pictured training with Anderlecht.
The Red Devils has been linked with a move for Paulo Dybala who is strongly linked to sign with Tottenham after Juventus reportedly accepted a £70 million bid.
Meanwhile, veteran Mario Mandzukic has also been rumoured with transfer to Old Trafford.
However, Spurs are said to be looking to get rid of Christian Eriksen, who is determined to find a natural ‘step up’ from Tottenham with United looking to table a bid for the midfielder.
United kick-off their Premier League campaign on Sunday, August 11 at home to Chelsea.
Kick-off is at 17:30 (SA time).
