[2] After his accident, Neșu started a personal foundation dedicated to children with motor disorders, at the same time receiving treatment for his paralysis from which he did not make a full recovery.

[2][3][4] He was transferred to Steaua București in 2001 for $6,000 and made his Divizia A debut on 21 April 2002, when head coach Victor Pițurcă used him in a 1–1 draw with Petrolul Ploiești.

[2][3][8] On 10 May 2011, Neșu got injured during a training session by colliding with teammate Alje Schut; he broke his cervical vertebrae, which left him paralysed in a wheel chair ever since.
