Paul Cook says John Sheridan deserves a "great reception" from Chesterfield's fans when he returns to his former club on Tuesday.
Sheridan parted company with the Spireites at the end of August following a disappointing start to the season after relegation from League One.
However, he delivered silverware during his three years at the Proavct Stadium as Chesterfield won the League Two title in 2011 and lifted the Johnstone's Paint Trophy last year.
"I hope it goes well for John in terms of the reception he gets - certainly not the result," said Cook, who became Sheridan's permanent successor in October following Tommy Wright's spell as interim boss.
"John is a seasoned professional, he's had his times at this club and he's produced some fantastic nights for this football club, so I'd like to see him get a great reception.
"I think John's history and his managerial record at this club will show what he's done, which was obtain a championship winning team and a cup final win at Wembley - and I hope that doesn't go amiss on our supporters. I'm sure it won't."
Sheridan returned to management with the Pilgrims in January with the Devon club in the relegation zone. Going into Tuesday night's game, Argyle are 19th in the table and three points above the bottom two.
