Pompey are just one point clear of the relegation places, with Norwich and Oxford United looming large in the rear-view mirror.
They have won six of their 24 league outings so far, and were on the receiving end of a 5-0 hiding from Bristol City last time out.
A win today would see them improve on last year’s FA Cup campaign, too, after they were dismissed at the first time of asking by Manchester United last season.
It remains to be seen whether Arteta will be able to call on Piero Hincapie for the match after he limped off at the Emirates on Thursday night, though Cristhian Mosquera is definitely expected to miss out.
