Manchester United manager David Moyes admits his team's lack of cutting edge is giving him serious grounds for concern following a shock home defeat by West Bromwich Albion.
Moyes' side have not scored from open play in the Premier League since their 4-1 victory at Swansea City on the opening weekend of the season.
The run continued when they were deservedly beaten 2-1 by West Brom on Saturday, making it three defeats in Moyes's first six league games in charge and United's worst start to a season since 1989.
Moyes had previously complained about a difficult opening to the campaign that saw his side take on Chelsea, Liverpool and Manchester City over the course of the first five games.
After heading to Shakhtar Donetsk in the Champions League in midweek, they travel to Sunderland next weekend before a pair of back-to-back home matches in the Premier League.
