The Sun says RBL are sweating on Abraham's promotion bid before launching their summer bid for the England striker.
Aston Villa will look to make his loan signing permanent if he takes them to the Premier League.
And he took a huge step towards achieving that by firing home the winning penalty in the shoot-out triumph over West Brom last night.
But Leipzig are also willing to offer him a £25million route to Bundesliga to join Jadon Sancho among the young British talent in Germany.
They have made Abraham, 21, one of their top targets.
