Frank Lampard eased the pressure on Chelsea boss Andre Villas-Boas with a late winner against Wolves in the Barclays Premier League clash at Molineux.The veteran midfielder celebrated his return to the starting line-up by converting a cross from Ashley Cole with two minutes remaining.Ramires had given the Blues a 54th-minute lead but Stephen Ward looked to have salvaged a point for the home side - until Lampard settled the issue.However, it needed an injury-time save from goalkeeper Petr Cech - who tipped over a close-range header from Kevin Doyle - to deny Wolves a point.Victory enabled Chelsea to end a four-game run without a win and, temporarily at least, pushed them back into fourth spot with Arsenal not in action until this evening.Villas-Boas would have taken heart from the performance of Fernando Torres, who started in the absence of the injured Didier Drogba and Daniel Sturridge.The former Liverpool player looked sharp and committed throughout the 90 minutes and there were signs of him returning to his best.Juan Mata also impressed in the centre of the park but Wolves' battling spirit meant they were always in contention with winger Adam Hammill causing plenty of problems.An early slip by Jose Bosingwa allowed David Edwards a shot at goal inside the first 20 seconds but it lacked power and Cech was able to save comfortably low to his right.A mix-up between Wolves defenders Christophe Berra and Ward allowed Torres to play in Mata but his cross-shot failed to hit the target.Torres was looking confident despite not scoring since October 23 and picked out the run into the box of Lampard.It needed Richard Stearman to make a fine tackle to deny the England midfielder a clear-cut chance.Lampard became the first player to be booked, for a sliding tackle on Hammill.
