( CNN ) -- Chelsea have closed the gap on leaders Manchester United at the top of the English Premier League after a John Terry header and a Frank Lampard double gave them a comfortable 3-1 win at Blackpool on Monday . Terry was left unmarked to nod home Lampard 's 20th minute corner to put the defending champions on their way to a second victory in a week -- following last Tuesday 's 2-1 home success over United . Blackpool were unlucky not to level before half-time when midfielder Jason Puncheon 's fierce low drive was tipped onto the post by goalkeeper Petr Cech . But Lampard doubled the advantage just past the hour mark when he converted from the penalty spot after substitute Salomon Kalou was tripped in the area by defender Ian Evatt . And the England midfielder was on hand again four minutes later when he slid the ball home after Kalou 's pass had split Blackpool 's defence wide open . But Blackpool continued to battle away and they scored a late consolation goal when Puncheon found the corner of the net after being set-up by James Beattie . The result means Chelsea stay in fourth place , nine points behind United although they do have a game in hand . However , Blackpool remain in relegation trouble and they lie in 15th place , just two points and three positions above the relegation zone . Meanwhile , in Spain 's Primera Liga , Deportivo La Coruna beat Real Sociedad 2-1 to improve their chance of avoiding relegation . Deportivo 's victory means they are up to 13th position , five points clear of the bottom three , while Sociedad are ninth and look clear of relegation danger .
Chelsea consolidate fourth place in Premier League after beating Blackpool 3-1 . A Frank Lampard double and John Terry 's header gave the visitors three points . The Blues have won their last two games against rivals Manchester United, but they are still without a win over Arsenal since October 2009. Blackpool remain in 15th place just two points above the relegation zone .
