And one man they have been linked with in recent days is Manchester City goalkeeper Joe Hart, who is now on loan at Serie A side Torino.
The England global is on loan at Italian top flight side Torino this season after becoming surplus to requirements after Pep Guardiola took charge at Man City.
LIVERPOOL goalkeeper Simon Mignolet has targeted further improvement after Jurgen Klopp's men edged closer to Champions League qualification. We have a goalkeeper playing a brilliant season at Huddersfield Town. "[Wilfried] Zaha, [Andros] Townsend, Christian, [Jason] Puncheon, they're extremely great footballers", Klopp said in Thursday's media seminar. Liverpool were one of the favourites to secure the signing of Hart this summer but Klopp will not be entertaining such rumours.
"We have to wait for this moment, if there's something else to say about this I would say".
"He is a fantastic goalkeeper, the goalkeeper of the English national team, the highest quality, but we have highest-quality goalkeepers".
"The number of goals we conceded is absolutely too high - it is really rare in my personal history that we concede goals like that big number, we will work on it 100%" Klopp said, as reported by the Daily Mirror. However, it is a good show of faith from the manager and should provide both goalkeepers with a sense of much needed confidence.
Klopp: "I like being here but I don't want to bother people with my presence if we're not successful".
But the Reds boss issued a more positive update on the fitness of midfielder Adam Lallana, who returned to outdoor training at Melwood earlier in the week. "We will see, I don't know in this moment". The former Liverpool striker is a formidable opponent in the air during open play and from set pieces.
Liverpool head into their clash with Palace off the back of their 1-0 win over West Brom last Sunday.
The Merseysiders, third in the Premier League, will be hoping to boost their hopes of a top-four finish, as well as extending their unbeaten run to seven matches. "At this moment he can not train".
Palace, who are 15th, have won five of their last seven games to move seven points clear of the relegation zone with six games to play.
The German revealed that the management staff and Henderson are in "intense talks to different departments" and "the medical department of course". He is not patient any more, I can tell you that.
