"Attack attack, attack attack attack!" Louis van Gaal hears it every time his team enters the pitch at the Theatre of Dreams.
The Old Trafford faithful have been spoilt with attacking riches over the years - Eric Cantona, David Beckham, Ryan Giggs and, of course, Cristiano Ronaldo all played fast, counter-attacking football with devastating results.
But, now with a new philosophy and none of those players to call on Van Gaal finds himself at a crossroads. His captain and leader Wayne Rooney is going through a wretched and barren time and although he may have recently broken England's scoring record, once the red shirt goes on he seems to lack the conviction and finishing prowess he has displayed during his ten years at Old Trafford.

Anthony Martial had an amazing start to his United career, but has gone somewhat off the boil and at 19 can hardly be expected to lead the line in every competition.
James Wilson has been loaned out to Brighton and Adnan Januzaj is still also out of the picture in Dortmund. This means the Dutch boss has limited options left to choose from, the first being to play Memphis Depay in the main striker role with Rooney just behind him.
However, Depay looks like he still needs to settle at the club before he is ready for the role. He is a player of undoubted talent, but still only shows this in brief flashes and looks to be suffering under the weight of his transfer fee.
The option the fans are crying out for is for, however, is a new striker who can score the goals that can take the club back to the top of the Premier League - where they belong.
In January, players of the highest calibre are rarely available and even if they are, the chances are they have already played in a European competition - making it nonsensical to buy.
The right purchase
But one name stands out above all others and he fits the player profile of Van Gaal to a tee - Saido Berahino. Not only is he lightning quick and a predatory finisher, but after his flirtation with Tottenham, he is still looking for a move away from the Hawthorns.
Tony Pulis remains hopeful their relationship can be repaired but it is clear that Berahino wants to play at the highest level and the Champions League could just be enough to tempt him into making the move to Old Trafford.
The United manager will also be attracted to the fact he will be able to play in Europe - should they qualify from their group - making him an obvious choice.
Will he be signed in January? We will see.
