Chelsea suffered yet another Premier League defeat on the weekend, losing 1-0 at home to Manchester United.
The Blues are on a barren run that has seen them fail to score a single goal in all of their last four league matches.
Saturday was the same story. Matheus Cunha's only goal of the game which came just minutes before half time ensured all three points headed back to Old Trafford.
And the frustration is clearly building among the Chelsea camp.
Frustrated Pedro Neto raged at ballboy against Manchester United
Pedro Neto, who started on the right flank and put in an average performance, was visibly annoyed throughout the game. So much so that the Portuguese winger even managed to clash with a young Stamford Bridge ballboy.
Despite Liam Rosenior naming an exciting attacking line, also including Estevao and Cole Palmer, Chelsea struggled to carve out chances.

Try as he might, Neto was also to blame for the Blues' lack of cutting edge in the final third; something they've failed to get right all year.
Mid-way through the first half, Neto was preparing to take a free kick but, as journalist Lloyd Canfield reported at the time, the 26-year-old was enraged by the ballboy's lack of urgency.
Neto felt the young ballboy didn't attempt to recover the ball quick enough which meant he missed the opportunity take a quick free kick.
The winger's frustrations were added to when he did eventually restart play but Malo Gusto then passed the ball straight back;Â a passage of play the former Wolves man would rather forget.
The cracks are beginning to show
While few will doubt the players' passion, Neto's outburst, even at 0-0 on Sunday, was the visible representation of the side's frustrations.
They're in a bit of a hole and are watching Champions League qualification disappear in front of their eyes. Although there is a chance the side could still play top European football next season, even without a top four finish, Rosenior won't want to leave it chance.
The Blues sit sixth, 10 points off Aston Villa in fourth, and now have just five more league games to make up as much ground as possible.
A potential FA Cup final, should the side get past Leeds United in the semis later this month, would certainly cushion the disappointment of their domestic capitulation though, so all hope is not lost yet.
