TOMMY Johnson switched to his preferred central striking role and scored a first half hat-trick as Aston Villa went goal crazy against Wimbledon at Villa Park. Johnson, who failed to score in five previous appearances for Villa, broke his duck with a vengeance, his treble coming in just 16 minutes. Dean Saunders (2) and an Alan Reeves own goal completed the rout all this after Warren Barton had given the shellshocked Dons an early lead. It was all achieved without former Wimbledon striker John Fashanu who was made a presentation on the pitch by visiting fans before the game to mark his nine years at the club. There were few early signs of the drama set to unfold as Warren Barton gave Wimbledon an 11th minute lead with a fine volley. But within 30 seconds Villa equalised when defender Reeves deflected a Saunders shot past goalkeeper Hans Segers. Johnson broke his Villa duck in the 22nd minute when heading in a right-wing cross from Gary Charles, and four minutes later capitalised on an Qyvind Leonhardsen mistake to make it 3-1. Johnson effectively ended the contest in the 38th minute when he turned home Shaun Teale’s shot following a Steve Staunton corner. But Villa did not take their foot off the pedal and Saunders completed the nap hand with a 20- yard rocket in the 48th minute. Saunders scored his 14th goal of the season from the penalty spot after Segers was adjudged to have brought down lan Taylor in the 67th minute. Then in the 83rd minute Dwight Yorke clipped the ball past Segers to complete the rout after good play by Johnson and Saunders.
