The Spaniard has faced criticism for failing to recreate the form he had at Liverpool before moving to Stamford Bridge in January 2011 for £50m.
Despite initially struggling to find his feet at the West London club, Torres is beginning to show impressive form following his winning goal in the Blues' 2-1 win over Manchester City yesterday.
"It looks to me like Fernando Torres could be back to his best at long last – I thought he was excellent in Chelsea's win over Manchester City," Lawrenson wrote in The Mirror.
"He's got the hunger back, and also half a yard of pace. He missed an easy chance early on and could easily have let his head drop, but he didn't. If Torres' improvement continues then it will be a godsend for Jose Mourinho."
Yesterday's victory has taken Chelsea to second in the Premier League table.
