Arsenal, however, must protect the value of a player they signed from Porto for around £35 million. However, reports suggest their realistic limit is below €10 million, potentially paid in instalments, leaving Arsenal with a difficult decision. A permanent exit would suit all the parties involvedFrom Arsenal’s perspective, allowing Vieira to leave permanently makes sporting sense. Keeping an unsettled player as a fringe option would benefit nobody, particularly with his Arsenal contract moving closer to its final stages.
