Southampton boss Claude Puel will resist any temptation to throw record signing Sofiane Boufal into the starting line-up before he is ready.
The 23-year-old midfielder joined the club from Lille in August but has so far made only two substitute appearances as he works his way back from a knee problem.
Boufal made his debut in last week's Europa League defeat by Inter Milan and then came on for the final 20 minutes of Saints' 1-1 draw with Manchester City in the Premier League on Sunday.
But fans hoping the Moroccan might be fit enough for a first start in Wednesday's EFL Cup fourth-round clash with Sunderland look set to be disappointed.
