Notts County central defender Julien Baudet has agreed to join Crewe after deciding not to sign a new deal with the Magpies.
The 27-year-old has had his contract terminated by mutual consent.
Baudet joined the Meadow Lane club in 2004 and went on to become a key member of the squad in the last two season, making 89 appearances in that time.
He scored 13 Magpies goals including a dramatic equaliser in the 2-2 draw with Bury on the final day of the season.
