The Magpies headed into this game fresh from a shock 1-0 victory away to Tottenham Hotspur last weekend, where Atsu made his first competitive appearance – playing for 73 minutes - after replacing injured Allan Saint-Maximin early in the first half.
He was in doubt to feature in the midweek League Cup penalty-shoot loss to Leicester City, but eventually did feature, replacing Matt Ritchie in added time in the first half.
The former Chelsea man started from kick-off this time in front of the Newcastle faithful, but it was the visiting Hornets who opened proceedings through Will Hughes after just two minutes.
Fabian Schar would go on to produce the equaliser for Steve Bruce’s men four minutes to half-time.
Atsu was on the pitch for 81 minutes before being replaced by Yoshinori Muto.
82' - A second change for Newcastle, with Atsu withdrawn for Muto. Watford, meanwhile, make their final substitution, with Deulofeu coming on for Gray. 1-1. #NUFC— Newcastle United FC (@NUFC) August 31, 2019
Having played 28 times in the Premier League last season, Atsu will be hoping to get into the thick of the action again after the international break, when the Magpies travel to Anfield to trade tackles with high-flying Liverpool on September 14.
