West Ham are eyeing Sunderland defender Daniel Ballard.
The former Gunners prospect played a key role in Sunderland's run to the Championship playoff finals last season.
The Sun says Ballard's form has brought him to the attention of West Ham chief Mark Noble.
West Ham chief scout Rob Newman checked on Ballard in March when he turned out for Northern Ireland against Finland.
The defender signed permanently for Sunderland a year ago.
