Manchester United and Arsenal made light work of their Premier League engagements on Saturday, comfortably beating Wigan Athletic and Portsmouth respectively.
Arsenal return to the top of the table, for 24 hours at least, after brushing aside beleaguered Pompey 4-1 at the Emirates.
About Diaby was the unlikely hero in the opening half, celebrating his first start of the season with two goals in the space of three minutes. The Gunners had dominated the opening exchanges with two goals the least they deserved.
Portsmouth pulled a goal back through former Spurs defender Younes Kaboul eight minutes before the interval but it proved to be nothing more than a consolation.
Arsenal continued to press in the second half and added further goals from William Gallas and Aaron Ramsey. However, Ramsey was on the field for Cesc Fabregas who looked to pick up an injury which could sour the victory.
Manchester United scored five goals at Wigan, without reply, with Michael Owen grabbing his first goal for the club.
Although United had been on top there was little to suggest United would produce four second half goes when the teams went in goalless at half-time.
But United proved they still have the goalscoring touch by scoring three times in nine minutes through Wayne Rooney, who moved onto 101 goals for the club in netting a brace, and Dimitar Berbatov. Owen then got on the scoresheet himself five minutes from time, finishing coolly when put through the centre.
Nani added the fifth in injury time with a quality free-kick.
Manchester City still have a 100% record in the Premier League this season after beating Wolverhampton Wanderers 1-0 at the City of Manchester Stadium. Emmanuel Adebayor again scored, netting on 17 minutes, but after City wasted numerous chances they had to settle for the narrowest of victories.
There was finally home joy for Hull City as they picked up their first victory at the KC Stadium since December. USA international Jozy Altidore, off the bench for his debut, was an instant hero in setting up another summer signing, Kamel Ghilas, to bag the only goal of the game against Bolton Wanderers.
Sunderland returned to winning ways with a 2-1 success at home to Blackburn, though Rovers will feel unfortunate to lose after rallying towards the end.
Gael Givet put the visitors in front at the Stadium of Light, but a brace either side of half-time from Kenwyne Jones turned the game on its head.
Saturday's other Premier League encounter saw Birmingham City and Stoke City play out a goalless draw.
