Sri Lanka have won the toss and elected to bowl in their World T20 clash against England in Delhi.
While Sri Lanka have played two league games so far, England have played three. The Lankans have won one and lost one, whereas England have won two of their three games.
A good win against a depleted Lankan side will not only enhance England's chances of semifinal qualification, but also become a cause of worry for other teams.
For the 2010 champions, the tournament so far has been a mixed bag. On a flat Wankhede deck, their batsmen fared well in both matches.
While Chris Gayle's blazing blade saw them lose against the West Indies despite scoring 182, it was sheer brilliance of Joe Root and Jason Roy which enabled them to chase down a mammoth target of 230 against South Africa.
Root, with scores of 48 and 83 in both matches, has looked in good form. But England's batting got thoroughly exposed against a much weaker but spirited Afghanistan side on a tricky Feroz Shah Kotla track in their last match.
It was Moeen Ali's rear guard action that saved them the blushes against the Afghans after being reduced to 85/7.
While English batsmen look comfortable against pacers when the ball is coming onto the bat, Herath and Vandersay might ask a few probing questions on a pitch conducive for slow bowlers.
Vandersay, who was summoned as a replacement for the injured Lasith Malinga, was impressive despite Sri Lanka's one-sided defeat against West Indies.
Using the feet to reach the pitch of the deliveries will be the key and skipper Morgan's IPL experience could come in very handy for the English batsmen, most of whom have little or no experience of playing on these surfaces.
