Mata, 25, has become a key player at the Bridge over the past two seasons. Boss Jose Mourinho has insisted publicly that Mata is a player he does not want to lose but he does not see him as a regular starter and that is unlikely to satisfy one of Europe's most creative players.
Manchester United have been linked with a move, while Tottenham are also understood to be watching Mata's situation.
But Arsenal believe they could provide the best option if he wishes to stay in London.
