It appears that Manchester United midfielder Bastian Schweinsteiger will not feature for the club again this season after suffering a knee injury on international duty.
And that will only compound a miserable first campaign in English football for the 31-year-old, who has failed to replicate the form shown at Bayern Munich in the Premier League.
The World Cup winner now faces an uncertain future at Old Trafford, particularly if manager Louis van Gaal makes way for Jose Mourinho this summer.

He certainly isn't the first underwhelming transfer to arrive at the Theatre of Dreams, though. Here are five other players who never quite lived up to the hype during their time at the club.
United believed they were signing one of football's finest strikers when they lured Radamel Falcao on loan from Monaco, but the Columbian's move, in hindsight, was a huge error of judgement.

The 30-year-old scored just four times during his spell at Old Trafford and was often left to play second fiddle to Robin van Persie and Wayne Rooney, who were higher up the pecking order.
Falcao's misery has continued with Premier League champions Chelsea and a move away from England now looks imminent in the summer.
ANGEL DI MARIA
Much like Falcao, United and Van Gaal thought they had signed a player capable of restoring them to the peak of English football in the summer of 2014.
But Angel Di Maria struggled during his solitary year at the club and, despite finishing the campaign with ten assists, lost his place to Ashley Young after a break-in at his home.
The Argentine has since rediscovered his best form in France with Paris Saint-Germain, helping Laurent Blanc's men secure the league title with seven games to spare.
Whilst there was no doubting the ability of Dimitar Berbatov, the Bulgarian never quite hit the heights many expected when he signed from Tottenham in 2008.
The classy centre-forward won two league titles during his four years at the club but was frequently overshadowed by Cristiano Ronaldo, Wayne Rooney and Javier Hernandez at Old Trafford.
Despite winning the 2011 Golden Boot, Berbatov missed out on a place in the Champions League final squad against Barcelona and was sold to Fulham the following year.
Sir Alex Ferguson missed out on Owen Hargreaves after the 2006 World Cup in Germany but got his man for a fee of £17 million the following year.
However, whilst he won the Champions League in 2008, the midfielder never became quite the player his manager thought he would be.
Hargreaves made just 27 league appearances during his four injury-plagued years at Old Trafford, eventually signing for rivals Manchester City on a free transfer in 2011.
Given his infamous reputation around the club, it seems laughable that United genuinely thought Kleberson would improve their title-winning squad of 2003.
The World Cup winner was signed with the belief he could emulate the classy performances of Paul Scholes in the heart of midfield, but never adapted to the English game.
He is still playing, currently with Fort Lauderdale Strikers in the MLS, but ranks as one of the worst signings in the club's history.
