Cape Town - Manchester United boss Ole Gunnar Solskjaer has opened up on why he feels his side struggled in their 2-0 defeat to Arsenal at the Emirates Stadium on New Year's Day.
Arsenal’s record signing Nicolas Pepe fired the hosts ahead after eight minutes at the Emirates and Sokratis Papastathopoulos added a second before half-time.
It was a richly-deserved lead for the Gunners and although United made changes early into the second period, Bernd Leno largely remained untroubled.
After back-to-back wins, United could have moved within two points of Chelsea in fourth place with success in the capital.
Instead, they struggled to create chances and it led to Solskjaer conceding they may enter the transfer market this month.
“After they scored the first goal, it seemed like they got loads of energy,” he added. “Their heads got loads of energy and our heads got a little bit tired and they were the better team.
“They were aggressive, regained the ball, we couldn’t find a way out of their press and it was hard to get the ball off them because I thought they played really well.
“It was a good game by two good teams and the goal just before half-time is a killer blow really because at 1-0 down you are in the game all the time, but at 2-0 you need a goal to get the energy to make them nervous again.”
