A statistical study of supernova remnants (SNRs) inside a galaxy is important for the understanding of the chemical enrichment and the energy budget inside a galaxy. The complete coverage of the Large Magellanic Cloud (LMC) and its surroundings provided by eROSITA allows us to investigate the SNR candidates proposed in radio and optical and to detect new SNR candidates never observed by another X-ray telescope before. Of particular interest is the increasing population of SNRs detected in the outskirts of the LMC. We present the most updated catalog of SNRs in the LMC. We compare the X-ray luminosity function (XLF) of the SNRs in the LMC with the XLF in the Local Group galaxies. Furthermore, we perform a morphology study on the X-ray SNRs in the LMC finding indications of a sub-sample of elongated SNRs.
