Diego Costa has reportedly asked Atletico Madrid to terminate his contract six months early in order to find a new club in the January transfer window.
The Spain international - who agreed a return to Atleti in September 2017, though was not able to play for them until January the following year - has endured an injury plagued 2020-21 that has restricted him to just seven appearances.
Atletico are said to be open to the possibility of offloading Costa should they find suitable cover, with Luis Suarez their only recognised out-and-out striker.
But how much of a loss would Costa actually be? Using Opta data, the time feels right to take a look at his attacking output in closer detail.
SCORING FEATS AND HELPING OUT
Costa does not exactly boast the best scoring record for a player with his reputation, netting only 12 times in 61 LaLiga appearances since the start of 2018.
Among those to have played at least 38 times during that period - the equivalent of a whole season - he ranks way down in 46th place for goals per 90 minutes (0.29). That is below the likes of Joselu (0.3), Lucas Perez (0.32), Juanmi (0.34) and Pablo Sarabia (0.37) across a similar number of matches.
The 32-year-old has often been praised for getting the most out of others, though that is not exactly reflected in terms of his number of assists.
He has set up a team-mate on only nine occasions across those 61 outings - an average of 0.22 assists per 90 minutes.
For context, former team-mate Antoine Griezmann (0.23) and current colleague Suarez (0.33) rank higher, with Barcelona talisman Lionel Messi (0.45) top by distance in that particular metric.
IMPACT ON THE TEAM
Eight of Costa's 12 LaLiga goals since returning to LaLiga have come via his right boot - including three penalties - plus three with his head. All but one of those goals came inside the box, with exactly half from open play.
But does Costa's presence in the side, as suggested by boss Diego Simeone in the past, have a positive impact on Atletico and the way they function?
In terms of average LaLiga goals scored per game it does, rising from 1.4 in the 67 matches Costa has not started, compared to 1.6 with him in the line-up.
However, Atletico win fewer matches when Costa is involved, with their 61.2 per cent success rate dropping to 51.2 per cent - or 2.1 points per game to 1.9 on average.
A STUTTERING SEASON SO FAR
Costa is no stranger to spending time on the sidelines, not least this season; he initially contracted coronavirus before then being ruled out with deep vein thrombosis.
That has restricted him to seven LaLiga appearances. Only two of those have been from the start, as he was named in the XI for wins over Granada and Celta Vigo.
He may only have netted twice but still boasts an average of 0.87 goals per 90 minutes in the Spanish top flight this term, second only to Suarez (0.94) among Atleti players.
Joao Felix is next on the list (0.58) having scored five goals in 12 outings, though the Portuguese has also chipped in with a couple of assists, something Costa has yet to do in 2020-21.
Costa also ranks highly in terms of shot conversion rate, having scored from half of his four shots this term, not including those to have been blocked.
Another metric he tops is touches in the opposition box, averaging 8.7 per 90 minutes. That is not only the most for any Atleti player but also the third highest in the league - after Barcelona pair Trincao (10.2) and Ansu Fati (9.08) - for those to have featured at least seven times in the competition this term.
Ultimately, though, Simeone is after a player who can not only combine all of these attacking aspects but also stay fit for a sustained period of time. For that reason, it could be that Costa's time with the club is drawing towards an end.
