Diego Simeone remains confident the goals will come for Jackson Martinez after the striker drew another blank in Atletico Madrid's 3-0 Copa del Rey last-16 second-leg win over Rayo Vallecano.

Angel Correa's 40th-minute strike and two goals from Antoine Griezmann ensured a 4-1 aggregate success and a place in the last eight for Simeone's men.

Griezmann's brace took his tally for the season to 16 goals while Martinez - who moved to Atletico from Porto in June last year for €35million - has just three to his name.

The Colombia forward was denied by Rayo goalkeeper Yoel moments before Griezmann's first 10 minutes from time.

Asked about the contrast between the form of Griezmann and Martinez, Simeone - who would not be drawn on questions surrounding the transfer ban imposed on Atletico by FIFA on Thursday - said: "They are situations with which one must live.

"But I liked Jackson's game a lot. The goals will arrive because he has them [in his game]. It is a matter of waiting."
