Watford face a battle to keep hold of Ikechi Anya.
The Mirror says Anya is a £4million target for Celtic - and they have not given up hope of signing the Hornets winger despite their ascent to the Premier League.
Anya, Scotland's international player of the year, has a year left on his contract at Vicarage Road.
And although Glasgow-born Anya wants to complete his amazing rags-to-riches story in the top flight with Watford, Celtic boss Ronny Delia is in hot pursuit.
