North London giants Arsenal have not won each of their last four meetings in all competitions including the Europa League clash on Thursday evening.
Portuguese Super League club Vitoria Guimares scored a late equaliser to secure a 1-1 draw at home to the Gunners in the Europa League.
The Victoria Guimares draw makes it four games without a win for embattled Arsenal manager Unai Emery who is in danger of losing his job.
The current winless run started with the 2-2 draw with Crystal Palace in their London Derby clash in the Premier League played at the Emirates Stadium.
Arsenal were two goals up before they were pegged back by their visitors.
The match would be remembered for the behaviour of former team captain Granit Xhaka towards the fans while he was substituted.
The Crystal Palace game was followed by the 5-5 draw at the home of Premier League leaders Liverpool in the fourth round of the Carabao Cup.
Liverpool went on to win 5-4 on penalties to secure their place in the quarterfinals where they will meet Aston Villa next month.
Arsenal drew 1-1 at home at home to Wolverhampton Wanderers in their league clash played at the weekend.
Shkrodan Mustafi gave Arsenal the lead at the home of Vitoria Guimares FC of Portugal in the last ten minutes before Bruno Duarte shared the points with an overhead kick in added time as the Gunners drop points for the first time in the Europa League.
