Alkmaar to prove solid test for goal-shy United
United coach and former striker Ole Gunnar Solskjaer watched in frustration as his side squandered opportunities to kill off the Gunners when a goal up on Monday, only for Pierre-Emerick Aubameyang to pounce and snatch a point with his only real chance of the game.
"We go 1-0 up and then we don't get the second goal that we want to get. That's the learning now for this time," he said after a 1-1 draw that left his side 10th in the Premier League.
"Be more cynical, clinical. There are so many games we have been 1-0 up."
Since their 4-0 thrashing of Chelsea on the opening day of the Premier League campaign, Solskjaer's struggling side have failed to score more than once in any match, and they will likely find Alkmaar a tough nut to crack.
Thursday's clash, being played in The Hague after the roof at Alkmaar's home ground the AFAS Stadion collapsed last month, will also provide an indication as to who will top Group L, with solid Alkmaar flying high in the Netherlands.
Alkmaar are third in the Eredivisie, just a point behind leaders Ajax and PSV Eindhoven -- who take on Rosenborg in Group D -- thanks in large part to a defence that has let in just three goals in eight league matches since the start of the campaign.
They also came away with a creditable draw at Partizan Belgrade last time out, while group leaders United huffed and puffed before squeezing past Astana.
Solskjaer also has a burgeoning injury crisis on his hands, with ESPN reporting that Paul Pogba aggravated an ankle injury at Old Trafford and could be left out of the short trip to the Netherlands.
Should he be ruled out, the World Cup winner would join forward Anthony Martial and defenders Aaron Wan-Bissaka and Luke Shaw as either doubts or confirmed absences.
In Rotterdam, two former European champions will face off when Group G leaders Porto travel to Rotterdam to take on Feyenoord, who will be looking to bounce back from their opening-day defeat at Rangers.
