(Reuters) - Aston Villa's upward trajectory under manager Unai Emery is no surprise to Arsenal boss Mikel Arteta who said on Friday he is expecting a tough game when he takes his Premier League leaders to Villa Park on Saturday.
Villa, who put in a dominant performance in their 1-0 victory over champions Manchester City on Wednesday, are up to third in the league. They have won 14 straight Premier League games at Villa Park and have also qualified for the knockout stage of the Europa Conference League.
