Ralf Rangnick bemoaned Manchester United's composure after they again slipped up when leading to draw 1-1 with Southampton on Saturday.

Jadon Sancho struck first after 21 minutes at Old Trafford with his second goal in three games, as many as he scored in his first 23 outings across all competitions for United.

However, just as they did at Burnley on Tuesday, Rangnick's side squandered their lead and were held after Che Adams' second-half equaliser.

It is only the second time in Premier League history that United have failed to win back-to-back matches despite being ahead at half-time in both, having last done so in December 1998.

Just four top-flight teams have dropped more points than United (13) from a winning position this season, and Rangnick expressed his concern after yet another failure to hold onto a lead.

"It was very similar to previous games, unfortunately," Rangnick told BBC Sport. "It is the fourth game where we were ahead but took one point instead of three. It is difficult to take but we have to accept it.

"It was a very good first half hour. I was pleased with our performance. We didn't allow them too many chances, but they had transitional moments in the first half and then scored an early goal in the second half.

"Then it was an open game, each team had chances. We had the clearer chances to win, but right now we are struggling to keep our composure and the structure for more than the first half.

"We have to understand where we are. [Southampton] won 3-2 at Tottenham. We got a point today, we expected three and needed three, but that is the situation.

"That is why there was a change of manager and why we are here."

Luke Shaw echoed his manager's frustrations as he stressed the importance of converting their good starts into wins.

"History is repeating itself again," Shaw added. "We started really well the first 20 minutes, got the goal and it just happened again. We know it's not good enough and it needs to change quickly.

"If we take our chances early in the game, it's a different story. We know we need to get better. We can't over-think it. We want to get in the Champions League and it's not good enough and there's no way we will get in Champions League if we keep dropping points.

"The most important thing at the moment is results. It's about picking up the points and we need to be climbing the table.

Rangnick, however, reserved special praise for Sancho, whom he believes is rediscovering the form that led United to spend £73million on the former Borussia Dortmund winger last July.

"This is the Jadon Sancho I know from the Bundesliga and the way he is playing at the moment is the best Jadon Sancho we have seen for Manchester United," Rangnick added.

United will look to make amends on Tuesday when they host Brighton and Hove Albion.
