Manchester United legend Paul Scholes has said that he believes Ole Gunnar Solskjaer is struggling to find the right balance between defence and attack at Old Trafford.
The Red Devils rearguard nullified Manchester City's attackers in Saturday's goalless draw in the derby, but United offered very little going forward themselves.
United striker Edinson Cavani was missing through injury, but Scholes thinks that United's problems in front of goal run deeper than the Uruguayan's absence.
"You go right back to that Tottenham game where they had a massive shock conceding six goals they had to change the way they were playing," Scholes said in quotes attributed to The Mirror.
"They had to play the two holding midfielders to protect the centre halves because they were giving chances away all the time. I thought Sterling was poor tonight, I thought [Aaron] Wan-Bissaka did well against him.
"Defensively, Wan-Bissaka throws himself into challenges, [Victor] Lindelof was as good as he probably has been and [Harry] Maguire was good. They had that protection, but it takes away from the attacking side then because you can't really think of any chances United created.
"It's compromising everything, they cannot get the balance right in the team. If they play one holding midfielder they look like they're going to score goals but look like they'll concede as well.
"They look much more solid with the two holding midfield players but then they don't look like they're going to score goals."
United's draw with their bitter rivals leaves them eighth in the Premier League table ahead of Thursday's trip to Sheffield United.
