Spanish giants Barca suffered a 5-2 aggregate defeat to French champions Paris Saint-Germain in the last-16 of the Champions League.
The defeat will inevitably lead to more speculation over Messi’s future but Koeman says the Argentine legend should be in no doubt that the club has a ‘great future’ ahead.
‘Leo has seen for quite some time that the team is improving thanks to all the changes we’ve made,’ Koeman said.
‘Particularly, we have young players of great quality. We’ve got a great future ahead. Leo can’t have any doubts about what the future holds for this team.’
On his team’s Champions League exit, Koeman added: ‘Okay, we are out, which is what counts in this sport. But we leave with good sensations.
‘We had opportunities to make things very complicated for our rival. We were the superior team in the first half, taking big risks at the back with man-to-man marking.
‘Really, we deserved more for that effort. It should at least have been 2-1 to us at half time. If we’d led at the break, the second half would have been a whole different affair.’
