The Liverpool manager opted to withdraw Dejan Lovren at half-time of the Premier League clash after the Croatia international picked up a booking amid a hostile welcome from his former supporters.
Martin Skrtel replaced Lovren as he made his return from a hamstring injury with Liverpool leading 2-0, but the Reds collapsed in the second half and lost 3-2 to Ronald Koeman’s Saints side.
The Slovakia international was heavily criticised for his calamitous return to action after a long injury lay-off.
While Aldridge felt Klopp was right to take off Lovren given the exceptional circumstances, the former Liverpool striker felt Toure would have been a better option to fill the Croatian’s void.
“I think Kolo Toure certainly has a strong argument for the fact it should have been him coming on. I think among Liverpool’s squad players Kolo has been excellent this season,” Aldridge told Liverpool Echo.
“He’s been class in the dressing room, in the Merseyside area when he’s been representing the club as an ambassador and he’s never let us down when he’s played.”
Liverpool’s 3-2 loss to the Saints on Sunday was their first Premier League defeat in four games.
