Barcelona defender Javier Mascherano has talked up the importance of Alexis Sanchez and Mesut Ozil in the Gunners squad as the Catalan giants prepare to face Arsenal on Tuesday.

Mascherano who has experienced what both players can do personally believes the Gunners should be taken seriously on Tuesday. Mascherano was Sanchez’s teammates at Barcelona before the forward moved to Arsenal and the Argentine has also faced Ozil on different occasions before. Speaking on Sanchez, Mascherano said:

“He delivered in the time he was here.”

“He was very involved. Maybe he just needed the challenge of having a greater part to play in another team.

“Now he has a huge role to play for Arsenal. He is crucial to what they do. His aggression and attitude is infectious.”

Luis Suarez replaced Alexis at Barcelona and When asked if both players are alike, Mascherano added:

“Yes. Totally, there is a touch of Luis Suarez. He is a fighter. He never gives up a single ball for lost. He is always going to give everything. And that is fundamental for any team.”

 The Argentine also had few words concerning Ozil.

“Özil is key. Everything revolves around him,” says Mascherano. “They have a very good midfield and they are always competitive. In the last two years they have raised their level, especially against the big sides.

“They are not going to change because they’re facing us.”
