The Brazilian centre-back reportedly remains a target for the Blues, who sent their sporting director to track his level of performance.
The focus of attention for Emenalo, it is believed, was to closely observe the performance of Brazilian central defender, Joao Miranda, who Chelsea were already linked with last summer, as per the Daily Mail at the time, having already snapped up Diego Costa and Filipe Luis.
At the end of this season, there is belief that a good offer could lure Miranda away from Atlético Madrid. The 30-year-old will have just one year left on the deal with his current club, whilst a move elsewhere could also present him with a final, big contract opportunity.
As for the performance the Chelsea sporting director will have observed at La Rosaleda, with Malaga holding Atletico Madrid to a 2-2 draw, that Miranda performed fairly well, despite his side dropping two valuable La Liga points on the road.
Antoine Griezmann had put Atletico in the lead, only for ex-Chelsea flop, Fernando Torres, to turn the ball into the back of his own net for the Malaga equaliser. Samuel put the home side ahead with a deftly lobbed finish, before Griezmann fired in his second of the game, earning Simeone's men a point.
Coincidentally and aside from the brace of goals from Man of the Match Griezmann, former Chelsea midfielder, Tiago Mendes, was one of the best players on the pitch according to ratings from WhoScored.com.
By stark contrast, for his own-goal and dismal display, Fernando Torres was considered one of the worst.
