The Hammers manager revealed that Valencia required stiches on his foot after the Ecuador international cut his big toe on a broken cup at his home.
We’ve gone to Arsenal a couple of times and got in front, but unfortunately the leads haven’t lasted very long
Speaking at his pre-match media conference on Thursday morning, the West Ham boss Allardyce played down Valencia’s chances of facing the Gunners at The Emirates.
“Enner has had an accident at home and has cut his big toe quite severely on a broken cup. It has been stitched,” said Allardyce.
“We’re not sure if he will be considered for this game. It was a freak accident.”
Valencia has scored four goals in 25 Premier League appearances following his move to Upton Park in the summer following an eye-catching performance at last year’s World Cup in Brazil.
Allardyce has seen his side tumble down the table since the festive period after the east London side were touted as potential European contenders earlier this season.
West Ham are winless in seven Premier League games ahead of their clash against Arsene Wenger’s side, and Allardyce admitted his Hammers squad have suffered from fatigue.
“Hopefully the little bit of rest physically and mentally will help us win more games in the last ten,” Allardyce added.
“I’ve been doing it for ten years and the stats say we should have a break as it reduces the risk of injuries in the New Year.
“We’ve gone to Arsenal a couple of times and got in front, but unfortunately the leads haven’t lasted very long. All we can hope is that we produce the level of performance we did against Chelsea and hope that is good enough.”
