Barcelona strike duo Lionel Messi and Luis Suarez plot Roma's downfall as Ernesto Valverde's side train on eve of Champions League last-eight clash

Lionel Messi is set to return to Ernesto Valverde's Barcelona starting XI when Roma visit the Nou Camp for Wednesday's Champions League quarter-final first leg.

After missing both of Argentina's matches during last month's international break, Messi only featured as a substitute at Sevilla on Saturday night when he came off the bench to score a late equaliser which preserved Barca's unbeaten record in La Liga.

But Messi should start up front alongside Luis Suarez against Roma. And the pair appeared to be plotting something as they were pictured in conversation during a training session at Barca's Ciutat Esportiva Joan Gamper base on Tuesday.

Andres Iniesta, Jordi Alba and Sergio Busquets were also seen chatting during a light session, which saw coach Valverde gather the whole group together for a team-talk.

Busquets broke his foot as Barca beat Chelsea on March 14 and has not played since, but he is expected to be passed fit and could start in midfield alongside Iniesta.

La Liga leaders Barcelona will start the two-legged tie as heavy favourites to beat Roma, who are currently third in Serie A.
