Unai Emery doesn't have a lot of luck against Barça. Whether managing Almeria or Valencia, the coach has never won in ten attempts, with five wins and five draws. His teams have scored 8 goals in this time, while letting in 19.
Not only has he never beaten Barcelona, but he has lost every time he has come to the Camp Nou, where he'll be back on Wednesday for the Copa del Rey semi final. He first came here back in 2007/08, when he was in charge of Almeria. He lost then, and then lost three more times as manager of Valencia – all of which were league games.
Goals for Messi
When Unai Emery came to the Camp Nou in 2007/08 his Almeria side lost 2-0 to goals from Henry and Messi. From the 2008-09 season onwards, it was as Valencia coach that Emery came to Barcelona, losing on his first visit by a heavy 4-0 thanks to a hat trick from an inspired Thierry Henry and another from Dani Alves.
Nothing changed the two seasons after that. In 2009/10 his side was the victim of another hat trick, this time from Messi (3-0). In 2010/11, Valencia actually took an early lead through Pablo Hernández. But Josep Guardiola's side managed to turn the game around with goals from Iniesta and Carles Puyol (2-1). In games at the Camp Nou, therefore, the goals have very much been in favour of the home side, who have hit the target 11 times and conceded just one.
