Real Sociedad manager Imanol Alguacil has said it is impossible to stop Barcelona's Lionel Messi ahead of the La Liga showdown between the two sides on Saturday.
The Blaugrana head to the Reale Arena level on points at the top of the table with rivals Real Madrid, who will travel to Valencia on Sunday. It's unlikely the Catalans will face a straightforward 90 minutes in the Basque Country, as La Real sit in an impressive fifth place in the table.
Minimising Messi's influence in the match will be key if Sociedad are going to take any kind of positive result.
