Arsene Wenger plans a major squad overhaul following another trophyless season and his scouting team is looking at a number of players at the moment.
Portuguese daily O Jogo has suggested that the Gunners watched Sporting Lisbon footballers Rui Patricio and Armindo Bruma in Saturday’s victory over Olhanense.
It is no secret Wenger is looking for a new number one and he has reportedly made the Portugal international his number one target.
Arsenal reportedly had several bid rejected for Patricio, but there is every chance the 25-year-old will be allowed to leave at the end of the current campaign.
Meanwhile, the Gunners are also showing interest in Armindo Bruma, who is wanted by Bayern Munich and Manchester United.
The 18-year-old winger has nailed down a regular starting berth at Estadio Jose Alvalade this term and he is predicted a bright future in the game.
