Martinez off to winning start at Wigan

Hugo Rodallega's stunning strike and a second-half effort by Jason Koumas secured the points for the visitors, who extended their unbeaten run in this fixture to five league matches.

The margin of victory could have been even greater with Rodallega seeing an effort cleared off the line and Charles N'Zogbia hitting the post, but as it was there was much to displease the Villa fans, who showed their unhappiness with a chorus of boos at the full-time whistle.

Villa boss Martin O'Neill handed full debuts to new signings Fabian Delph and Habib Beye, while Stiliyan Petrov was passed fit to start after recovering from a dislocated shoulder. Villa went with Emile Heskey and Gabriel Agbonlahor up front. But John Carew was unable to take his place on the bench after injuring his foot in the warm-up, Nathan Delfouneso instead getting drafted in.

Martinez also handed full debuts to two new recruits, Honduran midfielder Hendry Thomas and Jordi Gomez. Jason Scotland was on the bench. The visitors who had the best chance of a busy opening to the match, Gomez again pulling the strings with a lay-off for N'Zogbia - whose low shot was brushed on to the post by Brad Friedel.

Wigan's threat going forward was converted into the lead in stunning fashion after 30 minutes, Villa full-back Nicky Shorey's misplaced header sitting up perfectly for Rodallega, who dispatched a superb looping 20-yard finish over Friedel and into the top-left corner.

Villa almost got on level terms in the 39th minute when Ashley Young underlined his international class with a delightful 25-yard free-kick that brought an equally eye-catching one-handed save from the alert Chris Kirkland.

Seven minutes into the second period, Petrov hung up an inviting cross for Carlos Cuellar who should have done better than head wide. Moments later Agbonlahor had the chance to level in a goalmouth scramble, but Titus Bramble hacked to safety.

Disgruntlement in the stands increased after 55 minutes when the hosts fell further behind. N'Zogbia was the creator of the goal, his probing run from the middle of the park culminating in a precise lay-off for the onrushing Koumas, who kept his head to finish low through Friedel's leg from the left side of the area.

Villa pushed for the breakthrough in what time remained, Young the chief tormentor going forward but failing to find a killer ball in the final third. Confirmation it was not to be Villa's day arrived two minutes from the end when Heskey beat Kirkland to a loose ball and squared for Young to take aim at an open goal, only for the winger's goalbound effort to be brilliantly deflected to safety by Bramble.
