After completing a fantastic second season since returning to English football, which saw his side win the Premier league title and the Capital One Cup, Chelsea manager Jose Mourinho appears to be relatively happy with the current squad he possesses, and may not look to spend big this summer.
So far this transfer window, the Blues have signed goalkeeper Asmir Begovic from Stoke City and Radamel Falcao on loan from AS Monaco.
However, both were simply replacements for the two outgoing players of Petr Cech and Didier Drogba, with the former joining rivals Arsenal and the latter being released at the end of his contract.

Last week, the Premier league champions also had a £20 million bid rejected for Everton defender John Stones, but are expected to return with an increased offer for the 21 year-old Englishman, who is seen by Chelsea as a future replacement for club captain and legend John Terry.
But, after confirming his interest in Stones and praising the signings of Begovic and Falcao, Mourinho announced that his side weren't to spend big this summer, unlike their rivals.
He also confirmed that winger Mohamed Salah was to leave the club and Bertrand Traore and Victor Moses were to stay, although if one was to leave, they would soon be replaced.
Despite the fact the Portuguese tactician feels his current squad is good enough to retain the Premier league title that his side won so convincingly last term, there are some areas of his squad that may need adding if he wants to retain the title and possibly even attempt at winning the Champions League for just the second time in the club's history.
In Cesar Azpilicueta, Chelsea have by far the best left-back in the Premier League which is rather impressive considering the Spaniard is naturally a right back by trade. However, a new left-back will certainly be required due to the imminent departure of Filipe Luis to Atletico Madrid, only a year after he joined the club.
Cesc Fabregas and Nemanja Matic formed one of the best midfield partnerships in Europe last season with the former accumulating 18 assists in the Premier league, more than any other player, whilst the latter has transformed into a world class defensive midfielder since rejoining the club in 2014.
Although this is definitely an area not in need of repair, better cover may be required in case of injuries or suspensions to either one of the two.
Players such as John Obi Mikel and Ramires are good players, but Mourinho may look to better caliber of players this summer, with Zenit's Axel Witsel surely possible.
Last season, Chelsea's main three attacking midfielders were Eden Hazard, Oscar and Willian, with only January signing Juan Cuadrado as cover.
With Oscar very inconsistent despite his obvious talent and Willian not scoring the amount of goals required, the champions may need someone to come in and improve this already strong area and make Oscar, Willian and Cuadrado all battle for a place.
Atletico Madrid star Antoine Griezmann and Real Madrid playmaker Isco could be targets, despite Mourinho's comments about not strengthening, and both would be wonderful acquisitions for the side, potentially the final thing the team needs in order to win the Champions League this upcoming season.
Overall, despite Mourinho's comments, it still appears that the Premier League champions need one or two signings this summer in order to fight on all fronts next season.
It remains to be seen what the London club will do regarding this transfer window but with their new sponsorship deal and rich backing from owner Roman Abramovich, it is very unlikely the club will go the rest of the transfer window without strengthening.
