The Liverpool legend and Bundesliga title-winning coach with Bayer Leverkusen is the firm favourite to replace Slot, who has come under immense pressure in recent months.
Slot lifted the Premier League title last season but is struggling to grab Champions League qualification during the current campaign which is likely to see The Reds go trophyless.
Alonso, who is tipped to take over from Slot, was spotted in Paris alongside his wife, Nagore Aranburu, ahead of Liverpool’s first leg with PSG at the Parc Des Princes.
Now, Alonso’s agent Ibáñez has also reportedly been seen after he took a private jet from his home in San Sebastián to Paris earlier this week ready for the tie. Reports claim he attended the Liverpool loss, likely reporting back to Alonso after the clash.
Nagore was reportedly forced to turn off comments on her recent Instagram posts after being attacked with pleas from Liverpool supporters urging her husband to replace Slot as soon as possible.
Liverpool exited the FA Cup with a whimper, suffering a 4-0 defeat to rivals Manchester City at the Etihad which only adds to their loss in the EFL Cup to Crystal Palace and league position which is clearly worrying supporters.
Slot faces Fulham this weekend and if he suffers another defeat, talks with Alonso and his agent may speed up as there are limited games left for the club to secure European football for next season.
