Barcelona boss Luis Enrique has claimed that Lionel Messi is currently "in the best form possible".
The Argentine netted his 400th goal for Barcelona at the weekend as the Catalan outfit recorded a 2-0 win over Valencia in La Liga.
Messi has netted 46 goals in 46 games this season, including eight in the Champions League.
"Leo is in the best form possible going into the game and 400 goals is an impossible number. These figures are unique and unrepeatable," AS quotes Enrique as saying.
Barcelona will welcome Paris Saint-Germain to Camp Nou on Tuesday for the second leg of their Champions League quarter-final.
