As rumours of Diego Costa's move to Chelsea intensify, Liverpool fans will be left thinking what might have been, after they came close to acquiring the Atletico Madrid striker last season.
However, were Luis Suarez or Daniel Sturridge to suffer a significant injury, their attacking prowess would likely be significantly reduced.
Last summer, when rumours of Suarez's exit from Anfield were swirling at their strongest, Brendan Rodgers had made significant inroads into bringing Costa to Liverpool, to either play alongside the Uruguayan or replace him.
Football is full of "ifs and buts", and a front three of Costa, Suarez and Sturridge would almost certainly be the strongest in world football if the former Valladolid man had made the switch to Rodgers' side.
For what now looks like a modest sum, Liverpool and Atletico were discussing a £22 million deal for the forward which went as far as the player commenting on the possibility of moving to Anfield.
"I was close to leaving, Liverpool are a great team," Costa told Mundo Deportivo at the time. "But after fighting so hard and overcoming difficulties to get my place at Atletico, how could I leave?"
In reality, Liverpool probably backed down a little from the deal once it was clear Suarez was going to stay at the club, despite the very real possibility that a little more money for either Atletico or Costa would have secured him.
As it stands, Costa is now set to join rivals Chelsea for £32 million after a phenomenal season that could see the Brazilian-born Spanish international win La Liga and the Champions League, scoring 35 goals in 49 games.
Time will tell how much Costa punishes Liverpool if his transfer to the Blues goes through.
