The Blues ended Jose Mourinho's first season back in charge at Stamford Bridge without a trophy, but Chelsea appear set to splash the cash this summer in order to get back to winning silverware, with Atletico Madrid trio Filipe Luis, Tiago and Diego Costa widely expected to be arriving in West London in the near future.
Yet in order to keep bringing players into the club, Mourinho must also let some players leave. Defender David Luiz is set to be confirmed as a Paris Saint-Germain player, whilst experienced trio Ashley Cole, Frank Lampard and Samuel Eto'o have already left the club having seen their contracts expire.
Mourinho is expected to overhaul his strikeforce after watching his side struggle for goals at times this season, and whilst Eto'o has already gone, there could be yet more departures after it was today revealed that Senegalese striker Ba will hold talks with Besiktas over a move to Turkey.
It's no surprise after Besiktas tried to move for the former Newcastle United hitman in January, but Chelsea could be making a mistake by allowing the 29-year-old to leave the club this summer.
Admittedly, Ba is by no means the type of dynamic striker that will score the goals to lead Chelsea back to the summit of the Premier League - far from it - but towards the end of last season, Ba entered a rich vein of form, where he scored a number of important goals. Crucial goals against Swansea City, Paris Saint-Germain and Liverpool were vital to Chelsea's hopes at the time, and he came on strong when the Blues needed him most.
Compare that to the contributions of expensive Spaniard Fernando Torres, and it seems Chelsea are letting the wrong striker leave. The former Liverpool striker has been one of the biggest flops in Premier League history since his £50m switch in 2011, but he's done nothing to justify that fee.
Mourinho could of course choose to sell both, but after the departure of Eto'o - and the anticipated exit of Romelu Lukaku - Chelsea would be left without a recognised centre forward until Costa signs. And even then, they need squad players behind him who can contribute when it matters most - which is where Ba has thrived.
