He said: "The biggest challenge for the Royals from hereon is to achieve consistent winning results. The team has had an amazing run after the first game and the main objective now is to force our way into the semi-finals and then the final.
"I can also come back for the semi-finals and final should the team get there. But the next two home games will be big for us. It's going to be tough for me to get into the team; it depends on the balance."
Mascarenhas, who has signed a three-year contract with Rajasthan for an annual fee of $100,000, claims his English colleagues are keen to join him and experience the IPL experience.
He said "The England players are desperate to play in the IPL. Next year they will all put their hands up to come and play.
"Everyone has watched the IPL in England and what an amazing tournament it is. I have watched all the games. The IPL is big time news in the England newspapers."
