Team director Andy Flower remains convinced Andrew Strauss is the right man to lead England in Test cricket.
Strauss averaged 17.83 in the series as England surrendered top spot in the world rankings with a 2-0 defeat to South Africa.
England have lost six of 11 Tests in the last year, in contrast to the excellent form of the ODI side which is led by Strauss' Test opening partner Alastair Cook.
Strauss is retired from the limited-overs formats and will not be back in England colours until the tour of India in November, when Flower fully expects him to still be at the helm and back in form with the bat.
"He's a superb leader; he can certainly take our Test side on. There is no doubt about that," Flower told Sky Sports News.
"He deserves a little break, he's taking that now and will come back feeling refreshed.
"He would have wanted to score more runs in this series and that might have put us in better positions to win matches.
"But that goes the same for all seven of our batsmen. He'll come back, I'm sure he's got his thoughts very clear."
