Chris Wilder's first game back at Sheffield United ended in disappointment as Charlton Athletic snatched a last-minute winner through substitute Isaac Olaofe.

Teed up by James Bree, Olaofe stabbed the ball home in front of the travelling Charlton fans to send them into raptures and seal a 1-0 win at Bramall Lane.

The Blades, who parted company with Ruben Selles last week, were still on the hunt for their first victory of the season, having lost all five of their league outings and sitting bottom of the Championship heading into Saturday's game.

Despite dominating possession, Wilder's side were unable to make it count, and were left frustrated by a well-organised Addicks press, registering just one shot on target. 

The defeat leaves United, who were among the favourites for promotion ahead of the season, rooted to the bottom of the second tier without a point to their name.

Wrexham, meanwhile, extended their unbeaten record on the road to three games after they came from a goal behind to beat Norwich City 3-2 at Carrow Road, as they moved up to 15th.

Jack Stacey gave the hosts the lead just before the break, but a rapid response after the interval saw Phil Parkinson's side net three goals in the space of just 12 minutes, with Josh Windass grabbing a brace.

Issa Kabore provided two assists, including for Ryan Longman's effort, which was sandwiched between Windass' goals, with Jovon Makama's late goal proving nothing more than a consolation for Norwich.

Elsewhere, Southampton's difficult start under Will Still continued, as they capitulated against Hull City in a 3-1 defeat at the MKM Stadium. 

Striking the first blow in the 22nd minute via Kyle Joseph, the Tigers added a second and third in the second half. 

Having teed up John Lundstram to make it 2-0, Oli McBurnie got in on the act as he headed past Gavin Bazunu to make it three. 

While Adam Armstrong made the scoreline a little more respectable in the dying embers, the Saints are now without a win in the league since the opening day of the campaign, and sit in 19th, with Hull rising to 13th. 

While off-the-pitch controversy has made headlines in recent months at Hillsborough, Sheffield Wednesday were given reason to celebrate as they recorded their first win of the campaign by beating Portsmouth 2-0 at Fratton Park.

A sensational 12th-minute Barry Bannan free-kick opened the scoring, before George Brown doubled Wednesday's lead in the 50th minute to hand the Owls a hard-fought victory against a Pompey side on an upward trajectory. 

Data Debrief: Blades encountering troubles at both ends

Including their play-off final defeat to Sunderland last season, Sheffield United are on a seven-match losing run in the Championship – their longest such streak since at least the 2016-17 season.

In that run, the Blades have also gone five league games without finding the net, their worst scoring drought in that period.

Meanwhile, Southampton's terrible run has also extended into this season. They have managed only two wins in their last 34 league outings (eight draws, 24 defeats).

However, their impressive win at Portsmouth means that Wednesday are now unbeaten in their last six away trips to Fratton Park in the league (W4 D2) – winning three consecutively for the first time.
