Hamstrung Clasie in doubt for Southampton league opener

Southampton will not take any risks with Jordy Clasie ahead of the Premier League season, after the midfielder suffered a hamstring injury on Thursday.

Clasie was forced off in the 62nd minute of Southampton's 3-0 win over Vitesse in the UEFA Europa League's third round of qualifying - the 24-year-old's first competitive outing for the Premier League club.

With Southampton's new league campaign beginning on August 9 away to Newcastle United, Clasie may not be involved as manager Ronald Koeman made it clear he will not risk exacerbating the problem.

"Clasie had some hamstring problems - we will find out more tomorrow," Koeman said.

"It is possible he will miss the start of the season because hamstring injuries are always dangerous."
