MADRID: Lionel Messi scored twice, including a stunning solo goal, as Barcelona blew away Athletic Bilbao to win the Copa del Rey on Saturday.
The cup was won and lost in a whirlwind 12 minutes in Seville, which saw Barca score four times to clinch an emphatic 4-0 victory, with Messi at his devastating best.
Koeman took over a team at rock bottom, humiliated by a historic loss to Bayern Munich and wounded by the attempts of Messi to leave the club for free.
But this 31st Copa del Rey success for the club is a testament to progress made and Koeman will hope it not only helps convince Messi to stay but gives Barca momentum now in a neck-and-neck title race in La Liga.
“Despite the changes at the club and the young players, at Barca, you have to always fight for trophies,” Koeman said.
