The 20-year-old's stock continues to rise thanks to saves from Webo and Castro, and when the former stepped up with a second half penalty, the young shot-stopper was equal to his effort.
Recalled to the starting line-up and offered his experience to the back four, becoming involved in an intriguing battle with Emilio Nsue, before seeing red for bringing down the attacker inside the area.
Thrown back into the side and was a strong presence in the centre, competing well with Webo and latterly Castro, earning their clean sheet.
Moved back into the centre of defence rather than his conventional right-back role, and looked far more comfortable dealing with the physical nature of Webo competently.
The full-back was handed a rare start by coach Quique Sanchez Flores, and repaid his faith by netting the crucial opening goal with a neat header. Was impressive and solid defensively, too.
More physical than usual, protecting the central defenders by intercepting possesion, refusing to allow Mallorca to link up with the front two.
Superb through pass set up Forlan's goal and looks to be maturing into his role at the Vicente Calderon.
A more reserved display from the Portuguese, but sparked quick counter attacks whenever possible, and was more industrious than inventive.
Bizarre home debut for the Brazilian who seemed to be on the edge of the action for the first half, and who was replaced at half time.
José Antonio Reyes
Excellent display from the winger, whose teasing corner created Valera's opener, then got his own name on the scoresheet, showing great energy in the last minute to add gloss to the win.
The striker has been off form of late, and while he did not see much of the ball in this match, he was in the right place to convert the ball past Aouate and put his side in a strong position.
Never really forced into a save in the entire match, but was helpless for all three of Atletico's goals.
Faced with Merida and Antonio Lopez attacking on his flank, and was often overwhelmed, as was the rest of the Mallorca back four, who suffered an off night.
The experienced stopper was wasteful when attempted to build from the back, and was not as his solid best when forced into defensive duties.
The full-back did not get forward as often as his team would have liked, and struggled to deal with the trickery and pace of Reyes, who gave him a difficult evening.
Looked susceptible any time that Atletico Madrid attacked with pace, and lost Forlan for the crucial second goal that gave his team a mountain to climb.
J. de Guzmán
Constantly attempting to build and probe from the centre of the pitch, and despite his efforts often being in vain, he proved to be one of Mallorca's best performers on the night, despite his harsh late red card for a foul on Juanfran.
The midfielder was a willing runner but was alway on the verge of the action, and in the end had no impact on the outcome of the match.
He and Antonio Lopez enjoyed a decent tussle, which the winger won when Lopez was dismissed for bringing him down in the area, but his efforts were in vain as the kick was missed.
Has been in good form of late from his wide midfield berth, but this was a poor display from the Frenchman, whose shooting wayward and his link up play not of a sufficient standard.
The frontman suffered an injury and was replaced after just 26 minutes of play.
- 27 Joel Robles
Came on at half-time and continued his encouraging start to his Atletico career. Suffered late tackle from De Guzman that saw the Mallorca man dismissed.
Came on to replace Forlan as Flores set up his team to hold out for the win.
- 18 Álvaro Domínguez
- 8 Raúl García
- 32 Koke
Arrived with five minutes remaining, and showed awareness to play in Reyes for the third goal.
- 1 G. Lux
- 21 Crespí
- 17 Ayoze
- Edson Ratinho
- 27 Tejera
Came on midway through the first half and looked to be threatening, his touch and invention giving Atleti problems, but could not beat De Gea.
Thrown on as Mallorca chased the game but could not deliver a much-needed goal.
