The Super Eagles defender netted the opening goal as Leganes claimed their second win of their pre-season preparations with a 3-1 bashing of Eibar at the Butarque Sports Facility.
Only three days ago, the Cucumber Growers carved out a narrow 1-0 victory over FC Cartagena.
And on Saturday morning, Kenneth Omeruo helped Leganes made a brilliant start, nodding home the game’s first goal in the third minute from a Dani Ojeda’s corner.
Rosales and Jose Armaiz subsequently made it three goals for Jose Martí’s side before the break.
Quique, however, pulled a goal back from the penalty spot for Eibar in stoppage time.
Omeruo featured for 90 minutes in the game.
The centre-back scored one goal in 23 league appearances for the Cucumber Growers last season.
The Nigeria international is expected to leave the club this summer following their relegation to the Segunda Division.
In another friendly on Friday, Samuel Chukwueze found the back of the net for Villarreal, but it was not enough as Valencia secured a fine 2-1 win.
Chukwueze put the Yellow Submarines ahead in the 9th minute, but a Maxi Gomez double in the second half turned the tie around in Valencia’s favour at the Estadio de la Ceramica.
