Mikel Arteta has admitted that Thomas Partey 's injury is a "big concern" for Arsenal heading into the all-important run in.
The 28-year-old, who has been a pillar for the Gunners this season across his 24 Premier League appearances, limped off in the 75th minute of their shock 3-0 defeat to Crystal Palace on Monday.
With the pre-match news that Kieran Tierney could be ruled out for the rest of the campaign and will undergo surgery on his knee, Arteta's misery was compounded due to the loss of Partey, with Arsenal already limited in midfield.
