Losing striker Jamie Vardy to Arsenal could spark an exodus of players from Leicester City, former defender Gerry Taggart has said, adding that the move could be catastrophic for the Premier League champions.
Arsenal tabled a bid for Vardy before he left for the European Championship in France with the rest of England's squad on Monday, according to British media reports.
The 29-year-old was the joint second-highest scorer in the English top-flight last season and Arsenal's bid comes at an uncomfortable time for England, whose manager Roy Hodgson has banned players' agents from the team hotel in Chantilly to avoid his players being distracted.
Vardy scored 24 league goals last season as Leicester won the top-flight crown for the first time in their history, and was voted as the Footballer of the Year by the Football Writers' Association.
"The whole Leicester ethos over the last couple of seasons has been built around people like Vardy," Taggart added.
England open their Group B campaign against Russia on Saturday. Wales and Slovakia are the other teams in their group.
