He wrote for the Sunday World: "Jurgen Klopp's decision to substitute Mohamed Salah with half an hour to go against Chelsea on Thursday night was hard to explain - but nothing has made sense at Liverpool over the last two months.
"Klopp's decision failed to avert a FIFTH successive defeat on home soil and even though this tortuous season is not over yet, the Liverpool boss must be counting down the minutes until the last ball is kicked and he has been put out of his misery.
"I never thought I'd see the day when a Liverpool team would lose five successive matches at Anfield, but it's in the record books now."
A concerned Aldridge also said: "Sadio Mane was also having a bad night, yet Klopp took Salah off and it was a decision that will fuel the rumours about the Egyptian's future at the club.
"Salah's decision to speak to a Spanish newspaper in December suggesting he was a big admirer of Real Madrid and Barcelona, followed by the appearance of his mate on TV saying his pal wasn't happy at Liverpool must have set a few alarm bells ringing.
"Throw in his muted goal celebrations since then and Klopp's decision to leave him out of a few games and you have a chain of events that will create a few headlines.
"His agent also sent out a cryptic tweet as soon as Salah was substituted the other night, so it would be no massive surprise if pushes for a move this summer.
"From what we saw in the January transfer window, Liverpool don't have the finances to spend big in the transfer market.
"So they might need to sell before they can buy ahead of next season."
