Lionel Messi has advised Barcelona to sign Bayern Munich star David Alaba to help improve their defence according to a report on Spanish tabloid Diario Gol.

The Liga leaders are likely to make a move for Antoine Griezmann in the summer, but it is understood that Messi also wants to see the Austria international join the club.

The 25-year-old Austria defender is currently playing for Bayern Munich and has made 31 appearances for the Bundesliga champions this term.

Alaba can play at left-back, centre-back and in a holding midfield role – a position he is said to prefer and if Barca can promise him that, he may well be tempted by a move to La Liga.
