Napoli striker Edinson Cavani continues to read little into the ongoing speculation regarding his future.
With the summer transfer window soon to throw open its doors, rumours are intensifying as to where Cavani will be come the end of August.
The Uruguay international is among the most sought-after frontmen in European football - having taken in productive spells in Serie A with Palermo and Napoli.
He has become accustomed to fending off endless rounds of gossip, with each passing window bringing fresh reports of big-money bids.
Cavani insists he is paying no attention to the latest rumours, with his focus locked on events at Napoli until told otherwise.
He told Ovacion Digital: "Real Madrid, Chelsea and (Manchester) City are interested in me? I just think about Napoli.
"If an important offer were to come in, I will talk with president (Aurelio) De Laurentiis.
"I'm fine in Italy, I have grown as a man there and as a player with the Serie A experience."
McDonald becomes the third senior player to exit the Globe Arena this summer following in the footsteps of Nick Fenton and Will Haining.
Shrimps boss Jim Bentley told the club's official website: "Gary has been the model professional and been terrific to work with.
"He is a great trainer with a fantastic attitude and has hardly missed a game since he has been here.
"Like Nick and Will he was a player I would have liked to have kept but he wasn't able to accept the terms we could offer and he has opted to look for another club and I hope he sorts out a deal soon."
Bentley added that he has offered new deals to Lewis Alessandra and Jordan Burrow, while Danny Carlton will return for pre-season training having missed the majority of this campaign through injury.
However, Chris Holroyd will also not have his stay extended having joined Morecambe from Preston in January.
