Mumbai have 12 points from two games while Delhi has only two from as many matches.
With the likes of Gambhir, Sehwag, Mithun Manhas and Unmukt Chand in their ranks, Delhi boasts of a top heavy batting line-up but it didn't click against Gujarat in their last game where they could only manage a point.
Mumbai, on the other hand, have started their campaign in right earnest having registered back-to-back outright wins in away games against Haryana and Punjab.
Gambhir and especially Sehwag, who has had some lasting on-field memories with Tendulkar, will be battling to save his own career some 20 kms from the Wankhede Stadium.

Delhi chief coach Sanjeev Sharma said that Sehwag wouldn't be given any suggestion about his batting order.
"Viru would bat where he wants to. There is simply no advice for him. If he feels he can contribute in the middle order, we are happy to have him at that slot. He is too good a player to remain out of form for a long time," Sharma told PTI.
