Manchester United are keen on making a deadline day move for Bayern Munich's out of favour midfielder Marcel Sabitzer - but face a race against time to seal the deal.
The Red Devils are looking to strengthen their midfield after losing Christian Eriksen to injury for the next three months and Austrian international Sabitzer has emerged as a target as the 28-year-old searches for more game time.
Sabitzer has found himself frozen out at the Allianz Arena this season and has not started a game since before the World Cup in early November - during their 2-0 Champions League win against Inter Milan.
Sabitzer would add quality to Erik ten Hag's midfield alongside the likes of Casemiro, Scott McTominay, Fred and Bruno Fernandes, but time is running out to get the deal done with just hours remaining until the transfer window slams shut.
United have also been offered the chance to sign Atletico Madrid's Yannick Carrasco as they seek reinforcements in the wake of Eriksen's fitness blow.
Eriksen picked up an ankle injury after a forceful challenge from Andy Carroll during United's 3-1 win against Reading on Saturday, and has been ruled out for three months.
Ten Hag was quizzed on bringing in a replacement for Eriksen during his press conference on Tuesday ahead of Wednesday's Carabao Cup semi-final second leg against Nottingham Forest, but admitted that it will be difficult to sign anyone before the transfer window closes.
'On deadline day it's difficult. You can't make policy on such bad injuries, but we have players in the midfield department, good players. We have players who can fill the gap,' Ten Hag said.
'I think you can never fill that (gap) because every player has his own characteristics and identity.
'Another player will always fill in in a different way, but it doesn't mean you have to be less successful.'
Eriksen and Carrasco are widely regarded as different players, with the former operating almost exclusively in central midfield alongside Casemiro and Bruno Fernandes since arriving at Old Trafford last summer, while Carrasco tends to play out wide.
Carrasco has shown his versatility over the years by featuring in a more central role at times, though, and with United facing a busy second half of the season as they continue to play in four different competitions they could see him as a useful option to have in their squad.
Ten Hag has Fred and Scott McTominay to deputise for Eriksen, but may seek to bring in an extra body to help his side with their congested fixture list before Tuesday's 11pm deadline.
