Leicester City and Celtic are chasing released Southampton defender Martin Caceres.
The Sun says he has been contacted by Scottish champions Celtic as manager Brendan Rodgers looks to assemble a team capable of making it through to the Champions League group stages next season.
But he could also have the option of remaining in the Premier League with both Leicester and Watford making contact to sound out his interest.
Foxes manager Craig Shakespeare knows he has to add more quality to a defence that looked vulnerable for much of last season.
Watford have begun looking for new players for next season despite not having a manager in charge following the departure of Walter Mazzarri.
And Caceres is will known to the Watford hierarchy following his time playing in Italy.
