Chelsea manage Jose Mourinho says the record £200m shirt sponsorship deal with Yokohama Rubber will not dramatically affect the club's approach in the future transfer window.
The initial five-year agreement with the Japan-based tyre experts is the second biggest deal in English football history, worth a reported £40m-a-year, and underlines their increasing presence as a major club on the landscape of the global game.
Uefa's Financial Fair Play regulations, which have been recently breached by Manchester City and Paris Saint Germain among others, have been strictly adhered to by Chelsea.
The last summer transfer window saw Diego Costa and Cesc Fabregas arrive in big-money deals from La Liga, as David Luiz joined PSG while in January the signing of Juan Cuadrado was offset by Andre Schurrle's departure to Wolfsburg.
In November 2014, Chelsea reported a record profit of £18.4m for the financial year, breaking even for the third season in a row after continual loses during the early years of Roman Abramovich's tenure in charge.
However, such a healthy position, enhanced by the recent sponsorship announcement, will not alter the club's strategy despite the "very impressive" figures behind the deal according to Mourinho.
"I don't think it is important for the transfer window I think it is important for Chelsea football club," he told reporters. "It is fantastic for us. From the point of view of the numbers I am not allowed to speak about it, but they are very impressive.
"Obviously for a club like Chelsea who wants to be in control of a financial fair play situation this is a deal that gives us some more oxygen to be stable and to be in control of the FFP rules.
"It is a good deal but it is not a deal that is going to change Chelsea's way of thinking forever.
"We are always trying to be balanced in everything we do. So we try and anticipate the next market and the next market will be like the last ones and Chelsea try to make some investment and Chelsea will try to make some money.
"Player after player and I think we are getting more credibility as sellers because they are normally players that goes to clubs and show their quality."
