But Watford turned down it down.
It was Newcastle United's first offer on the table, and some suggest the Toon owner will be back with an increased bid of £3million later this week.
However, the Herfordshire outfit have placed a much higher valuation on the centre-back and are looking for £5m.
Adrian "Aidy" Joseph Mariappa (born 3 October 1986) was born in England, and of Fijian descent.
He progressed through Watford's youth academy, and has spent his entire professional career at the club.
During that time he has made over 200 appearances for the club, including 19 in the Premier League, and has captained the team.
