Sporting Lisbon could lose their best player
Third seeds in the group, Sporting Lisbon, enjoyed a superb campaign in the Portuguese Primera Liga last season, but have lost manager Leonardo Jardim to AS Monaco and defender Marcos Rojo to Manchester United since then. With central midfielder William Carvalho also seemingly set for the exit, potentially to either Manchester United or Arsenal, the Lisbon side are likely to have seen their side torn apart by the time their Champions League campaign kicks off.
