Sports Mole rounds up all of the latest transfer news in La Liga on Wednesday, January 13.

Wednesday morning's La Liga transfer talk news roundup:

Manchester United 'battling Real Madrid, Barcelona for Yusuf Demir'

Manchester United have reportedly emerged as contenders to sign Rapid Vienna forward Yusuf Demir.

The 17-year-old has made 23 first-team appearances for the Austrian club, finding the net four times and laying on a further three assists.

Real Madrid are considered the favourites to land a player described as one of the next big stars, while Barcelona have also been linked in the past.

According to Defensa Central, however, Man United are also now in the running to sign the Austria Under-21s international.

Demir is said to be available for as little as €10m (£8.94m), with Rapid not against the idea of cashing in later this year.

Barcelona 'want Manchester City's Sergio Aguero on a free transfer'

Barcelona are reportedly interested in signing Manchester City striker Sergio Aguero on a free transfer this summer.

The Argentine's current contract expires in June, which means that the 32-year-old can talk to European clubs about a move away from the Etihad Stadium.

The Sun reports that the Catalan club have been alerted that Aguero is yet to negotiate a new deal with City and are hopeful of beating Spanish rivals Atletico Madrid to sign the striker.

French champions Paris Saint-Germain, who are now managed by Aguero's compatriot Mauricio Pochettino, are also interested in the City man.

Aguero, who has spent nine years with City, has won four Premier League titles, five EFL Cups and one FA Cup during a trophy-filled spell in Manchester.

The forward, however, has suffered with a knee injury for the majority of the 2020-21 campaign and has only featured nine times in all competitions so far, scoring just twice.
