Betting tip: A much-changed Barcelona should get this sorted fairly easily ahead of El Clasico
All eyes will be on this weekend, but Barcelona will want to take an advantage back to the Nou Camp.
More dropped points left Barcelona six points behind Real Madrid ahead of a crucial El Clasico at the weekend.
Bet365 make Hercules 12/1 with Barcelona priced at 2/11
Luis Enrique will be disappointed with Barcelona's recent form, but travelling to San Sebastian is never easy and they traditionally drop points there against Real Sociedad. They hadn't scored in their two previous visits, so a 1-1 draw isn't the end of the world.
It does leave them 6 points behind Real Madrid and Enrique will have to decide whether he is to risk first team players here. Andres Iniesta has been out injured and may return for the weekend, but will not feature here. Ideally, Barcelona will hope to build some momentum going into Saturday's clash and this could be the ideal opportunity on the West coast of Spain.
Javier Mascherano is another who will not feature after picking up a suspension in last season's final.
Lionel Messi didn't train on Monday and could be a doubt for this game. Barcelona fans will be hoping they wrap the Argentinian in cotton wool ahead of El Clasico. Gerard Pique did not train either.
Samuel Umtiti has recovered from a muscular injury and will feature in the squad.
Hercules will be relishing the match-up with Barcelona, especially considering the Catalan side's current form. It might be the perfect time to face them.
They are currently 6th in Segunda Division B Group 3 and will fancy their chances of at least taking something from the home leg.
Only Real Madrid have eliminated Barcelona in the last six seasons from this competition, so it's an almighty task that awaits Hercules.
Barcelona are likely to get the job done, but it's unlikely to be by a 5 or 6 goal margin.
Back 3-0 Barcelona at 15/2 with Bet365
Hercules will look to restrict the La Liga outfit to few chances so expect a low scoring first half.
Back exactly 1 goal in the first half at 2/1 with Bet365
And Highest Scoring Half - Second Half at 20/21 looks a decent bet too
