The Argentine has revealed he is feeling good as he works his way back to full fitness following hamstring problems in April
The Blaugrana saw their dominance in Spain in recent years ended last season when Jose Mourinho's Real Madrid romped to a record points tally to deny Pep Guardiola's side the trophy.
However, Tito Vilanova has guided the Catalans to being on the verge of taking back the Primera Division crown and, with a victory against Atletico Madrid set to guarantee it mathematically, Messi has expressed his excitement at the thought of wrapping up La Liga and returning to full fitness.
"We won [against Betis] and we are one step from the title," he said on his Weibo social media profile. "I felt really good in the minutes I have played - I'm happy!"
The Argentine was out of action during parts of April because of a hamstring injury and many pundits highlighted his sub-par performance and subsequent absence in the Champions League semi-final legs against Bayern Munich as key to their exit.
Wrapping up La Liga would go some way to healing the wounds left from that 7-0 hammering at the hands of this season's Bundesliga victors.
