Aston Villa became the latest title challenger to trip up on a weekend of surprising results in the Premier League, losing 1-0 at home to Everton on Sunday after a defensive blunder. After Villa center back Pau Torres gave the ball away on the edge of his area and goalkeeper Emi Martinez fumbled a soft shot, Everton striker Thierno Barry was on hand to supply a deft finish for the only goal in the 59th minute. Villa could have climbed above Manchester City to second place and trimmed the gap to leader Arsenal to four points with a win.
