*In-form Christian Benteke scored the only goal as Aston Villa beat Tottenham to move six points above the relegation zone.* Benteke headed in Leandro Bacuna’s cross as Villa boss Tim Sherwood got the better of his former club. Villa deserved their victory and almost had a second when Gabby Agbonlahor hit the post from Benteke’s flick-on. They had to see it out with 10 men after Carlos Sanchez was sent off for a second booking late on. Tottenham striker Harry Kane struggled to get into the game, as did most of his team-mates. If Sherwood keeps Villa up, he will owe much of it to Benteke, who is the top scorer in the Premier League since the manager’s appointment. The Belgian has scored eight in his last six Premier League matches, having scored two in the 16 before his arrival. As well as moving closer to Premier League safety, it will be doubly sweet for Sherwood against the club who sacked him as manager in May. Sherwood gave Kane his first top-flight start last season and claimed last month he stopped the club selling the striker. Kane, alongside Benteke, is one of the in-form strikers in England - having scored 11 in his previous nine league appearances. And he perhaps repaid his old manager with a quiet performance at White Hart Lane. Kane was aiming to score the goal that would make him the first Tottenham striker to reach 30 in a season since Gary Lineker in 1991-92. He had a few half chances but failed with a 30-yard snapshot in the first half, and a curling effort over the crossbar after the break. His frustrations in front of goal were echoed by team-mate Christian Eriksen, who has now not scored in 12 games having netted 11 in the first 30 of the season. The signs were ominous for Villa when they lost defender Ciaran Clark to injury in the first half, and Bacuna looked like he was going to have to go off with a knock of his own. But the Dutch full-back played on and had a role in the game’s deciding moment, whipping in a cross as Benteke beat defender Federico Fazio to head home off the post. Agbonlahor almost wrapped up the win just before the break when he hit the post from the edge of the box after Benteke flicked a header onto him. Spurs brought on £60m pair Erik Lamela and Roberto Soldado but Villa defended well and Fabian Delph almost scored a second late on with Michel Vorm having to deny the midfielder. Sanchez made things more difficult for his side at the end when he was shown a second yellow card for a late tackle on Danny Rose, but they held on.
