Both players were poised to join the Anfield club but now seem likely to remain where they are, at least until the summer.
Maddock highlights Barcelona's stubborn stance on Tello, unwilling to allow their young prodigy to depart given their growing injury concerns—as Guillem Balague also highlights for Bleacher Report.
Tello has made just two starts this season, the last of which was in October against Valladolid when the young attacker created the first two goals in a 4-1 win.
Maddock does, however, highlight the possibility of a permanent summer deal, when Barcelona would have Gerard Deulofeu returned from Liverpool's Merseyside rivals Everton.
As for Salah, the Egyptian winger has been garnering attention for the past two European campaigns with FC Basel.
Many media outlets, including David Anderson of the Daily Mirror and talkSPORT's Ian Abrahams, envisaged a January move to Liverpool, but it now seems that won't be the case.

Maddock rates Salah at around the £9 million mark, with that price proving the stumbling block for Brendan Rodgers who knows the player will become cheaper as his contract winds down.
Given the time it takes so many newcomers to acclimatise to the Premier League, Maddock doesn't anticipate extra being spent for a January move.
Still just 21, Salah has been a key player in two successful seasons for his Swiss club.
Which player would do better at Liverpool?
He created several key goals en route to last season's Europa League semi-finals and continued his form in this year's Champions League, scoring the winner against Chelsea.
Salah and Tello are both the type of young, fast, high-energy players Rodgers is renowned for coveting.
They would be capable of making an impact, suiting Liverpool's high-tempo offence and offering more innovative quality in the final third.
If both deals are indeed pushed back until the summer, it would come as a blow to Liverpool's current push for Champions League qualification.
