The Argentina defender indicated his disappointment with the defeat to Middlesbrough and insisted that the goals will come sooner rather than later
Marcos Rojo is concerned by Manchester United's lack of goals after Louis van Gaal's men drew blanks in each of their previous two fixtures.
United followed up a 0-0 draw at home to local rival Manchester City last Sunday with a penalty shootout elimination at the hands of Middlesbrough following a 120 goalless minutes in the last 16 of the League Cup, also at Old Trafford.
The Argentine believes the team's difficulty in finding the back of the net cost it on Wednesday and needs to be addressed quickly.
