Paul Pogba, David de Gea and Romelu Lukaku will all consider leaving Manchester United if the club fail to qualify for next season's Champions League, according to a report.
United are currently trailing a four-team race for two remaining places in the Premier League's top four, with Sunday's 4-0 defeat at Everton leaving them three points off the pace ahead of Wednesday's derby against Manchester City.
Ole Gunnar Solskjaer's side have now lost six of their last eight matches across all competitions, and The Guardian reports that a number of key players are beginning to consider their futures again following such an alarming dip in form.
De Gea has been embroiled in contract talks with the club for some time, and his current deal expires next year after United triggered a 12-month extension.
Pogba, meanwhile, has been heavily linked with a move away from Old Trafford at various stages this season, with Real Madrid, Barcelona and Juventus all understood to be interested in the Frenchman's signature.
Lukaku has fallen down the pecking order since Solskjaer's arrival in December and could also look to leave in search of both first-team football and Champions League football if the Red Devils miss out on the top four.
United made it to the quarter-finals of the Champions League this season but were knocked out by Barcelona earlier this month.
