Barcelona host Getafe in La Liga this weekend. Two teams whose fortunes couldn't be more different.
The visitors have failed to score in six of their last seven matches, losing all of those six and drawing the one in which they scored. Barca have remained unbeaten in all competitions since last October - that is the size of the task facing a club that haven't won at Camp Nou this century.
Getafe manager Fran Escriba has recently laid into his players accusing them of not being willing to 'die for the shirt'.

Teetering on the precipice of relegation, it's clear that the Madrid-based team need the points. And quickly.
But the likelihood is they'll have to wait at least another week before banking them. Let's take a look at three things that could affect the outcome of this one.

If there's one small chink of light for Escriba's side it's that Arsenal in the Champions League follows this one and there's little doubt Luis Enrique will want all of his best exponents fit and firing for that one.
Whilst there won't be wholesale changes made to Barca's starting XI, at least half of the squad are likely to be rested.
Where that benefits Getafe is down the left side of the Catalans' defence. Thomas Vermaelen and Jeremy Mathieu have shown themselves to be an awkward combination and one that doesn't work at the best of times.
If they can be got at in the opening exchanges, we could see the game take on a very different complexion.
May the force be with him
The unfortunately named Yoda has just about the hardest job on the pitch - marking Lionel Messi.
With the Argentinian in such devastating form, as he showed last time out against Eibar, the left back will need as much help as he can get to try and stop the world's best player.
Barca are looking for their 37th game in a row unbeaten, an unprecedented mark for the club and just shy of the European record of 43 set by Juventus.
Messi has been a huge part of the same, contributing goals and assists aplenty.
Yoda has been Getafe's best performing defender of late but he'll really have his hands full here.
When Sergio Busquets is in position, Barcelona's transitional play is a lot smoother and quicker.
The defensive midfielder has that enviable quality of always seemingly being able to pick out the correct pass time after time.
It's hugely noticeable when he isn't patrolling his normal sentry.
An unsung hero but a hero all the same.
Javier Mascherano will likely revert to his more natural position to cover and he'll provide an excellent alternative of course.
But he's no Busquets.
If Getafe's attacking four work the lines well enough there is gold to be mined centrally.
