Andres Iniesta has handed Barcelona a fitness boost ahead of Tuesday's Champions League quarter-final second leg against Paris Saint-Germain.

The Spaniard picked up a back injury in the first leg last week and consequently sat out Barca's 2-0 win over Valencia in the league at the weekend.

However, the midfielder returned to first-team training on Monday morning and is expected to be available for the European match at the Camp Nou.

Iniesta's performances have been called into question this season, but the 30-year-old is expected to go straight back into the midfield alongside Sergio Busquets and Ivan Rakitic.
