UEFA Europa League re-start on Wednesday with the fourth round of the group stage.
Arsenal travel to Afonso Henriques to face Vitoria Guimaraes in Group F.
Arsenal are top of the group with nine points and Guimarães are bottom of the group.
Vitoria won only one victory in eight previous encounters against English clubs in all competitions (three draws – four defeats), a victory over Aston Villa in September 1983.
However, Arsenal have managed to win just once, in their last seven away games against Portuguese clubs (3 draws – 3 defeats), at the expense of Sporting Lisbon in the Europa League last season.
Vitoria are aiming to avoid losing four consecutive European competitions for the first time since September 1998.
Arsenal are looking to win their first four group games, either in the Europa League or in the Champions League, for the second time in their history, after winning the first five games in the Champions League “2005-2006”.
Arsenal striker Gabriel Martinelli scored in his first two Serie A appearances this season, and the only player to score in his first three games for Arsenal was Marouane Chamakh in 2010.
