West Ham United have reportedly entered the race to sign Celtic defender Virgil van Dijk.
The 23-year-old Dutchman has been linked with a move to Arsenal in recent weeks as Arsene Wenger looks to strengthen his squad at the back.
However, the Hammers are now keen to bring the highly-rated centre-back to Upton Park, according to talkSPORT.
Scottish champions Celtic are understood to want around £7m for Van Dijk, who joined the club from Groningen in June 2013 for around £2.5m.
Van Dijk has three years remaining on his current contract with the Hoops.
