Diego Costa continued his stellar play and Chelsea remained undefeated following their 3-0 victory over Aston Villa Saturday at Stamford Bridge. Costa netted his eighth goal of the season and the Blues further padded their substantial lead atop the Premier League table.

Following his transfer from Atletico Madrid, Costa’s been nothing short of a revelation for Chelsea, providing the Blues some insurance in the 59th minute for the eventual 3-0 final score. Willian and Oscar would also tally their first goals of the term and keeper Thibaut Courtois registered his second clean sheet.

The three points increases Chelsea’s total to 16 on the season, while Aston Villa missed an opportunity to possibly bump the Blues from first place. By the day’s conclusion, third-place Villa could slip as low as seventh.

Wire-to-wire Chelsea’s attack applied pressure, racking up eight shots on goal, nine corner kicks and maintaining a 63-37 possession advantage.

Oscar started things in the seventh minute. Willian recovered his own blocked shot just to the right of the net and found his Brazil teammate in front of the net for the goal and 1-0 lead.

Villa and keeper Brad Guzan would clamp down for the rest of the second half, until Costa made his mark. Tested from all sides, Guzan totaled five saves.

But once again proving dangerous anywhere close to the net, Costa headed home defender Cesar Azpilicueta’s cross to top right corner and the Blues had the match at hand.

Wilian capped his and Chelsea’s day with the final goal in the 79th minute. Costa tried to get on the board for a second time and Guzan made a solid save, but it allowed Wilian to swoop in for the rebound and tap a shot into the bottom right corner.
