Atalanta midfielder Giacomo Bonaventura scored a goal in either half this afternoon to guide his side past relegation-haunted Siena in Serie A.
Bonaventura made the breakthrough after three minutes when he collected a pass from German Denis before smashing past Gianluca Pegolo from 20 yards.
Siena responded in an effort to defend their proud home record, with Alessandro Rosina and Andrea Consigli forcing saves with strikes from range.
Denis went close with a header in the second half before Bonaventura wrapped things up with a cool finish from close range.
Atalanta are now nine points clear of the relegation zone after recording only their second victory in 11 matches.
