Valuation of perquisite - lease rent

I am currently staying on lease taken by my employer and rent payment is Rs. 7500 p.m. The certain amount is getting is added as perquisite in gross salary upon which the employer is deducting tax at source from my salary.

Please let me know any way apart from investment under 80 C, I can save tax on this perquisite amount even though the rent is being directly by employer to the landlord and nothing is coming to me. Will submission of rent receipts to employer get me tax relief from this tax.
