Chelsea boss Thomas Tuchel expects Reece James to miss England duty through injury despite being selected.
On Thursday, James was named in Gareth Southgate's squad for the World Cup qualifiers against Andorra and Hungary.
Tuchel said the decision to include the 21-year-old right back must be a "misunderstanding".
"When I saw it I thought that maybe Reece goes with the water polo team for England, because right now he trains in the pool," he joked.
"So I was a bit surprised, but I understood that he was selected for the football team.
"This will not happen because Reece is training in the pool right now.
