Arsenal and Manchester City are considering bids for Celtic centre-back Virgil van Dijk, reports the Daily Star.
The Dutch defender has been earning rave reviews in the Scottish Premier League this season, following his £1.6million move from FC Groningen during the summer.
Gunners boss Arsene Wenger has been credited with an interest in bringing Van Dijk to the Emirates Stadium, and is ready to offer £10million in order to make the transfer happen.
However, Arsenal face competition for the player's signature from Manchester City, with Manuel Pellegrini also on the lookout for defensive reinforcements at the Etihad Stadium.
Neil Lennon will be eager to keep Van Dijk at Celtic Park until the end of the season at least, but admits that the player might be destined for bigger and better things, after tipping him to break into the Holland national team.
"It's inevitable, if he keeps going and progressing the way he is, that he'll become a Dutch international," said the Bhoys boss. "He makes it look easy.
"People seem to think he has a laid-back attitude, but his work ethic is very high and he's a kid who wants to get better."
Lennon added: "I'd like to think Virgil would get a chance with his country."
The 22-year-old has made 29 appearances in all competitions for Celtic this season, scoring three goals, and has been watched by scouts from both Arsenal and Manchester City on a number of occasions.
