Frank Lampard was delighted to see Chelsea spend big in January and is backing the new boys to come good.
Blues owner Roman Abramovich backed coach Carlos Ancelotti in the winter window, providing over £70million for new recruits.
That cash was used to acquire Fernando Torres for a British record £50million from Liverpool and Brazilian defender David Luiz for £21million from Benfica.
Both men have been thrust immediately into action at Stamford Bridge, with Chelsea keen to bed them in as quickly as possible.
Luiz shone on his first start against Fulham on Monday, with Petr Cech bailing him out after conceding a late penalty.
Spanish striker Torres is yet to hit the heights expected of him, with no goals scored in his first two outings, but the Blues are confident he will provide value for money.
Lampard insists the arrival of the former Reds ace has helped to raise spirits within the camp, and believes he will be back among the goals once expectations return to a more realistic level.
"He's made a huge difference," said the England international.
"No, he hasn't scored in two games but all the spotlight is on him.
"There's a huge responsibility, people are looking to him to do it instantly, but he will make a difference to us.
"He's a top-class player, he has boosted the lads already and for sure will come good, he's going to add to us in a big way.
"David Luiz has come in as well and has been fantastic."
Lampard admits he was surprised to see Chelsea dig deep during the transfer window, but feels the club needed a cash injection to help keep them competitive.
"I was slightly surprised but it was very exciting and I was pleased," he said.
"It's a huge boost to have such quality players that we needed at the time.
"We haven't spent much in recent years compared to some by our standards, but last season we won the double and this was a good time for us to go into the market. I'm just thankful we've got the funds to do this."
