Celtic are chasing Liverpool midfielder Lucas Leiva.
The Daily Mail says Brendan Rodgers is forging ahead with key improvements in order for his squad to make Champions League progress.
Lucas, who signed a long-term Anfield contract when Rodgers was manager there four years ago, will be allowed to leave for free this summer.
The lure of Champions League football could persuade the 30-year-old to consider Celtic. He, in turn, would bring cast-iron experience at the top European level.
