Lionel Messi is fit to start for Barcelona after treatment on kidney stones in midweek as Celta Vigo visit Camp Nou.

Messi missed the Copa del Rey semi-final second leg at Valencia because of the procedure but is back at the first opportunity, Luis Enrique having named a weakened side in the 1-1 draw at Mestalla and restoring his big names here.

Claudio Bravo returns in goal with Dani Alves, Gerard Pique, Javier Mascherano and Jordi Alba making up the defence.

Sergi Roberto gets the nod in midfield with Sergio Busquets and Andres Iniesta, and the MSN is together in attack as Lionel Suarez and Neymar join Messi.

Eduardo Berizzo makes one change from the side that drew 1-1 with Sevilla in their last League outing, Josep Sene coming in for Theo Bongonda.

That means Sergio Alvarez is in goal behind a defence comprised of Jony, Hugo Mallo, Gustavo Cabral and Carles Planes, a graduate of La Masia.

Daniel Wass and Nemanja Radoja make up the midfield pairing with John Guidetti supported in attack by Sene, Pablo Hernandez and Claudio Beauvue.

Some reports do though suggest Wass and Radoja will have Hernandez with them in a three, and Sene and Beauvue will occupy the flanks.
