Sunderland striker Fabio Borini was undergoing a medical in Italy on Thursday as he closed in on his move to AC Milan.

The 26-year-old flew to Milan on Wednesday as the fine details of the move were ironed out, and the Serie A club posted photographs of him having tests at the La Madonnina Clinic on their website on Thursday morning.

It is understood Borini will move on an initial season-long loan deal before completing a permanent £5.3million transfer next summer.

He had two years remaining on the deal he signed at the Stadium of Light during the summer of 2015, but has struggled for form since his £10million permanent switch to Wearside from Liverpool.

Borini scored 2 goals in 24 league appearances last season.

The Italian is one of several players on whom the Black Cats hope to cash in as they attempt to re-shape their squad for life in the Sky Bet Championship following relegation from the Premier League.
