Hat-tricks, hell-raising and high treason: 10 huge Clásico debuts
3. Gary Lineker (1987)
Lineker signed for Barcelona after his Golden Boot-winning exploits at the 1986 World Cup and did not disappoint, netting 21 goals in 41 games during his first season in Spain.
That included a remarkable Clásico hat-trick in a 3-2 win over Real Madrid with three typically clinical finishes. His first was predatory instinct, after stretching to meet a cross from the right to send the Camp Nou into a frenzy.
Then came the second after some wing wizardry from Roberto Fernandez Bonillo, who evaded two challenges and saw his shot palmed away, only for Lineker to follow it in from close range once again.
He completed his treble by capitalising on a defensive error before dinking over goalkeeper Francisco Buyo. Welcome to Spain, indeed.
4. Ronald Koeman (1989)
Koeman remains the greatest goalscoring defender of all time, and his Clásico début was a sign of things to come. The Dutchman joined Barcelona from PSV in 1989 and set the tone for a fruitful spell with the Catalan giants by netting twice from the spot in his first appearance against Madrid.
After Hugo Sanchez slotted the visitors into an early lead from 12 yards – a penalty given away by Koeman – Barca hit back through Julio Salinas, before the Dutchman displayed his own nerves of steel.
The first spot-kick was placed inch-perfect into the far corner; the second slotted coolly down the middle to set his team on their way to a 3-1 victory. He netted 14 goals that season but it wasn't enough to launch Barca any higher than third, Real finishing 11 points ahead as champions.
