Cape Town - Juan Mata says Manchester United need to find the target more often if they are to get back to winning ways, this following their 1-1 draw with West Ham on Sunday.
Diafra Sakho had given the Hammers a second-minute lead before Zlatan Ibrahimovic rescued a point with a headed goal on 21 minutes.
It was the club's fourth consecutive home draw, and Mata, along with team-mate Jesse Lingard, feels the side are not creating enough in the way of clear-cut goalscoring chances.
In his weekly blog, the Spaniard wrote: "A few days ago, we beat Feyenoord in a good game. We were playing to stay in the Europa League and the team delivered; we enjoyed ourselves on the pitch and scored several goals.
"So far in the Premier League, though, we haven't found that consistency, that winning streak that is so much needed and that we're working so hard to achieve.
"We know we must find the target more often to score more goals. We are doing what is more difficult: being able to create those chances, and now we have to take them."
United will have a chance to redeem themselves against West Ham on Wednesday in the League Cup, with Lingard, who conceded the free-kick that led to the opening goal, adding: "We're playing really well but we keep drawing. The performances are there - it's just [a matter of] putting the ball in the back of the net.
"It's four draws in a row with numerous chances - the luck's not there at the moment. But we have to concentrate on the game on Wednesday now.
"We've got high standards this season and for every competition we're in, our aim is to win. So it's good we have another game so quickly and we want to bounce back against West Ham."
This has been United's worst start in the league for 27 years as they sit in in 6th position on the standings, eight points off fourth-placed Arsenal.
Jose Mourinho was sent to the stands for the second time in recent weeks and could face a two-match ban after kicking a water bottle in reaction to referee, Jon Moss booking Paul Pogba.
