The Sharks will travel down to the West Country looking to make it two wins in a week over Redpathâ€™s Gloucester, having pipped the Cherry and Whites 13-11 at Edgeley Park in the league last Saturday.
But Redpath has warned his old club to expect no favours as Gloucester prepare to begin the defence of their LV= Cup crown at Kingsholm on Saturday.
Sale will welcome back a whole host of players from the World Cup, with Tony Buckley and Richie Vernon among the returning Sharks.
But it is Redpathâ€™s compatriot Dickinson, who the Scot is particularly wary of having spent the last four years coaching him down at Kingsholm.
â€œAlasdair Dickinson was back for them last week and got a bit of time off the bench,â€ said Redpath, who played 80 times for Sale and amassed more than 30 points for the Stockport-based club. â€œHeâ€™s a player we know very well â€“ we know what heâ€™s capable of.
â€œWith it being a home game last week for Sale, I think it was an easier way to come back into it, and Iâ€™m sure heâ€™ll be desperate to get back playing regularly for them.
â€œHe moved on from Gloucester to play some rugby because he felt his opportunities were limited here.
â€œAnd Nick Wood has been fantastic for us again this year, but Iâ€™m sure Dicko will be desperate to come back here and try to do one over on us â€“ heâ€™s a very talented individual.
â€œHe got one over last weekend so hopefully it wonâ€™t be 2-0 or I wonâ€™t be too chirpy.â€
