Sevilla must not allow Lionel Messi's superb record against them to distort their broader focus on Barcelona, Pablo Machin has warned.
The Blaugrana's superstar captain boasts a personal best 33 goals in all competitions against Sevilla, who head into Saturday's crunch home fixture without a win in three La Liga matches.
Sevilla beat Barca 2-0 in the first leg of their Copa del Rey quarter-final tie last month, only to crumble to a 6-1 defeat at Camp Nou on Messi's return to the starting XI.
The 31-year-old Argentina great has netted 22 times in as many La Liga appearances this term and shapes as the key figure in a match billed as pivotal in the champions' bid to defend their title.
