Now Marco Silva’s side are looking to clinch their first home win against the north Londoners since a 2-0 triumph in 1987.
Arsène Wenger brings his side to Vicarage Road for Saturday’s tea-time kick-off having won four in a row in all competitions, a run which will have gone some way towards easing the pressure on the Frenchman.
But Wenger will know only too well that his side are only ever one result away from crisis and a trip to face a Watford team buoyant after rescuing a point in stoppage time at West Bromwich Albion and riding high in eighth is far from ideal.
The Hornets have problems at centre-back where reigning Player of the Year Sebastian Prödl is a doubt with a hamstring issue. If the Austrian is passed fit he should take the place of Adrian Mariappa.
In the last couple of games Silva has gone with Capoue. But the former Tottenham man is languid and slows the play down. Against an Arsenal side who are known for their speed of play, the Frenchman could be a liability.
Up front Silva has another dilemma. Skipper Troy Deeney made his first start of the season in the 2-2 draw at West Brom prior the international break. He took the place of club-record signing Gray who had opened his account for the Hornets a week prior at Swansea City.
Isaac Success, who has yet to make a Premier League appearance this term, is also out after undergoing surgery on a leg issue.
