Costa has enjoyed a fantastic season in a hugely impressive Atletico Madrid side.
Diego Simeone’s team currently sit top of La Liga and have dismantled all who have came before them on the European scene.
But regardless of the form Atletico have shown in this campaign, it seems the Brazilian-born Spaniard will be leaving for pastures new this summer.
Here we take a look at Costa’s top 10 goals, all of which show why he could be the difference in Mourinho’s quest for Premier League and European domination…

1. The Power
It’s no secret that Chelsea have lacked a powerhouse striker since Didier Drogba left the club and here, Costa showed strength a determination to lose his marker.
A perfectly executed overhead kick, one that misfiring Fernando Torres could only dream of at the moment.
2. Tap Ins From Set Pieces
Jose Mourinho has had Samuel Eto’o, Fernando Torres and Demba Ba at his disposal this season.
None of which have the predatory instinct which Costa possesses. His movement is exemplary, as he showed by finishing off this corner kick.
3. A Cool Head
Chelsea may have Eden Hazard, Oscar and Willian, but they lack a forward who can keep their head when it comes to goal scoring.
Costa is a cool customer and possesses a Suarez-like-gift for making it look all too easy.
4. He’s Not Bad In The Air
Chelsea may have a number of players who are decent in the air, with Terry, Ivanovic and Luiz all capable, but none of their strikers are great with their head.
A striker who is so adaptable and flexible is a rarity in the modern game, making Costa a special case.
5. Can Score Against The Big Boys
The big stage clearly doesn’t bother the Spanish international, as he showed against Real Madrid with this curling finish.
Time will tell if he can keep his composure at the World Cup, but it’s something Chelsea are lacking.
6. Scores The Scrappy Goals
While Costa can score beautiful goals that are endlessly replayed and revisited, he’s also shown he doesn’t care what they look like, just as long as they end up in the net.
Costa can also read his teammates movements and has a perfect understanding with the wide players at Atletico.
7. Pace To Burn
As well as having a tactical mind, Costa is also an incredible athlete, both strong and able to move.
He’s quick off the mark and unlike an aging Samuel Eto’o, has plenty of miles left to run.
8. Technical Ability
There are very few strikers who can rival Manchester United forward Robin Van Persie for technique, especially on the volley.
But Costa scored this sensational goal, one that even the emphatic Dutchman would be proud of.
9. He’s Got A Bit Of Skill
Costa, as mentioned above, is very adaptable and flexible.
He’s a game changer, someone who can create a bit of magic out of nothing.
In a side which has sorely lacked creativity over the last few weeks, Costa would flourish.
10. And He’s Not Too Shabby From The Penalty Spot…
Atletico’s road to the Champions League Final involved playing Chelsea in the semi-final… and of course you-know-who got on the score sheet.
It may have been a penalty, but Costa’s was taken with absolute precision and with Lampard edging closer to the Stamford Bridge exit, Mourinho will need a trusted penalty taker next term.
