England attacking midfielder Dele Alli missed team training on Thursday as he bids to recover from a thigh injury in time for the side's second World Cup Group G encounter against Panama.
The Tottenham player picked up the knock during the 2-1 win over Tunisia on Monday with Alli tweeting that he was working to get back to full fitness.
“Frustrating to have picked up a slight injury on Monday. Will do everything in my power to get back to full fitness asap,” he wrote.
England take on Panama in Nizhny Novgorod on Sunday before completing the pool phase against Belgium in Kaliningrad next Thursday.
