Arsenal manager Mikel Arteta suggests there is little to worry about regarding Kieran Tierney's fitness.

The Scottish defender was struggling in the latter stages of their win against Southampton.

Fans were concerned that Tierney had suffered another injury, but Arteta suggested it was cramp.

The Gunners got a 2-0 win over the Saints to push them forward in the Premier League.

"Kieran was cramping," Arteta told Arsenal.com.

"He hasn't played two games together in the last seven or eight months and he was suffering.

"The weather is different to Scotland and he needs to adapt to it."
