Interim manager Benitez blamed the Blues' unprecedented series of major trophy failures on a lack of depth and variety in a playing pool that has also been riven by injury and suspension.
Benitez has come under increasing fire for his tactics and team selection after his side blew another golden chance to end their season with silverware in Wednesday's Capital One Cup semi-final exit at the hands of Swansea.
The Eden Hazard ball boy saga stole what might have been even more damning headlines about Chelsea's limp performance during this week's second leg at the Liberty Stadium.
Having begun the season competing on seven fronts, the soon-to-be-deposed European champions have now surrendered five pieces of silverware, four of them in semi-finals, finals or one-off matches.
They now have only two trophies to play for - their Barclays Premier League title hopes are all but over - with Sunday's FA Cup fourth-round tie at Brentford looking a must-not-lose game.
Confirming he had spoken to Chelsea's billionaire owner about transfer targets after Sunday's win over Arsenal, Benitez said: "We had a good conversation the other day but I have to concentrate on football and the game and tactics and all these things. That is my job."
Benitez spent much of Friday's pre-match press conference dropping hints he did not have enough resources at his disposal and when it was suggested that was what he was effectively saying, he replied: "Yeah, I know. When I talked with them [the board], I gave them my opinion and the club, they listened to me.
"They gave me their opinion, so we share opinions and we have these conversations and that's it."
Benitez denied Chelsea were guilty of poor pre-season planning ahead of a campaign during which they are playing an unprecedented number of matches.
But he was clearly hinting at a lack of numbers being behind the failures for which he is personally accountable: in the two trophies that were the most winnable this season - the World Club Cup and League Cup - as well as the demise of a league title challenge.
Benitez said: "The money that was spent before and was spent recently is different, and the other teams are also stronger, they are spending money.
"When you analyse the stats, you have to put in context or they don't have any value.
"It's not just about winning trophies.
"It's a key part of the game but the way and the tools that you have to win these trophies, that is the key."
He added: "The team is scoring more goals, conceding less goals.
"You can see that we have more balance but still we have some problems that we have to manage in these games.
"We have the styles or the characteristics of our players, for playing in a way that you have to manage.
"Some games you cannot and you have to change, and we don't have the other options.
"It's a style of football that we have to create with the players that we have, so we have to carry on.
"We cannot play long balls and try to win second balls like other teams. We have players that they have quality and we have to try to play this style of football."
Benitez's excuse that Chelsea were only able to play one way was intriguing, given their summer spending spree was focused precisely on recruiting the kind of talent he currently has at his disposal at the expense of more physical players.
He justifiably pointed to injuries to key men and the loss of John Obi Mikel and Victor Moses to African Nations Cup duty, while also alluding to the fact the club had spent just £7million on Demba Ba during his reign.
Sunday's trip to Griffin Park will see as many team changes as Benitez dares to make, with Hazard's suspension and David Luiz's injury further restricting his options.
The Spaniard admitted the game was a good one for captain John Terry to make his first start since November.
"I think he's progressing, he is doing well, so I think he will have a chance to play."
