Southampton midfielder Jack Cork has revealed that he has been impressed with the ability of teammate Adam Lallana.

Lallana's performances for the Saints this season was rewarded with an international debut for England in November, and Cork believes that the playmaker has the ability to make an impact with a top European club.

The 24-year-old told reporters: "He was running past people in training and I was saying that 'it is crazy how good he is'.

"There is no reason why Adam couldn't fit into any of the top sides in Europe or world football because he is that good."

Lallana has spent his entire career at Southampton, making 250 appearances for the club since making his debut in 2006.
