The news will be a disappointment to Pochettino, who had joked that he would have been prepared to parachute Jackson into Anfield if it meant having him available.
Pochettino said: “If it means we have a one per cent more chance to win the game for sure we will try it! But I don’t know if he is brave enough to jump.
“We are waiting. All I can say is that maybe he will be there. The other day Ghana lost and were out and Inaki Williams arrived a few hours before and played in the second half to beat Barcelona in the Copa del Rey. Why can’t Jackson arrive and score the winning goal?”
Jackson, who Pochettino admitted had been missed during his time at the Africa Cup of Nations, will now be back in time for Chelsea’s game against Wolverhampton Wanderers at Stamford Bridge on Sunday.
Chelsea are set to loan young midfielder Andrey Santos to their sister club Strasbourg for the rest of the season. Santos was recalled from Nottingham Forest after barely playing at the City Ground and will look to gain experience in Ligue 1.
There is also a chance that Chelsea’s 18-year-old Brazilian striker Deivid Washington could be allowed out on loan for the rest of the season before the transfer window shuts on Thursday night.
