Former Liverpool midfielder Lucas Leiva has announced that he has been pulled out of training by his Brazilian club Gremio after a heart issue was detected in a routine screening.
Lucas, 35, joined Gremio from Italian giants Lazio earlier this year, having initially left the South American club for the Reds as a 20-year-old in 2007.
The 24-times capped Brazil international played 346 times for the Reds across his decade on Merseyside, winning the League Cup in 2012 and proving crucial in the settling-in periods of players such as Philippe Coutinho and Roberto Firmino.
