AC Milan on Thursday announced the signing of Swiss left-back Ricardo Rodriguez, the third player captured by the resurgent seven-time European champions, on a four-year deal expiring in 2021.

Rodriguez, a 24-year-old who has 45 caps for Switzerland, joins the Serie A giants from Bundesliga side Wolfsburg, where he has played since 2011.

Milan, recently sold to Chinese investors by long-time club owner Silvio Berlusconi, have already bought Ivorian forward Franck Kessie (Atalanta) and Argentinian centre-back Mateo Musacchio (Villarreal).

Milan finished sixth in Serie A to seal a place in next season's Europa League.
