Aston Villa's miserable season suffered another damaging blow as a controversial penalty - converted by skipper Rickie Lambert - earned fellow strugglers Southampton a 1-0 victory at Villa Park.Villa defender Enda Stevens appeared to make no contact on Saints player Jay Rodriguez before he went to ground just inside the box but stand-in referee Mark Halsey - a late replacement for the ill Chris Foy - thought otherwise.Lambert made no mistake with his 34th minute spot-kick to move Nigel Adkins' side above Villa and complete a double. The harsh reality is Villa have now taken only one point from their last five league games and look set for a season-long battle to stay up.Although the penalty award was highly debatable, Villa were well below par in the opening 45 minutes and looked vulnerable on the counter-attack. They improved during the second half with Christian Benteke and Andreas Weimann posing a threat.
Benteke looked sharp in the early stages and had a shot on the turn blocked by Jos Hooiveld at the expense of a corner. But Villa were almost caught-out on the counter-attack after Lambert's first time pass found Rodriguez in yards of space. He cut into the box and slid the ball across Brad Guzan but Villa skipper Ciaran Clark was on hand to clear.
Southampton were looking dangerous and Rodriguez glanced a header just wide of the far post from Jason Puncheon's cross. Puncheon then created space for himself inside the Villa box after a a neat turn and shot over when he should have at least tested Guzan.
But then came the hotly-contested spot-kick which put the Saints ahead. Stevens appeared to make no contact on Rodriguez before he went to ground just inside the box. Villa protested in vain and Lambert sent Guzan the wrong way from the spot for his ninth goal of the season.
Luke Shaw was finding plenty of space to venture forward and Guzan blocked his shot from a narrow angle. Villa boss Paul Lambert brought on Barry Bannan for Holman at the start of the second period and his side showed more purpose.
Artur Boruc parried Andreas Weimann's left-footed effort and then Benteke hooked the ball over the bar after Artur had denied Stevens. Guzan was relieved when Puncheon crashed a fierce low drive against the post.
Villa staged a late rally and Boruc kept out Benteke's header. But he was powerless to stop Nathan Baker's header which crashed against the bar from substitute Barry Bannan's corner. Benteke then shot wide after Boruc had bravely saved at the feet of Gabriel Agbonlahor as Saints survived to seal their second away win of the season.
