Brocchi signs for Lazio
Thursday 28 August, 2008
Milan continue to trim their squad and have officially announced the sale of midfielder Cristian Brocchi to Lazio.
After adding Ronaldinho and Mathieu Flamini to their ranks, the Diavolo found Brocchi to be surplus to requirements.
Brocchi made few starts last term in spite of playing 29 times in 2006-07 - a career high number of outings.
The 32-year-old who spent the 2005-06 season on loan to Fiorentina has joined Lazio on a permanent basis with the fee believed to be around £2.2m.
Lazio had been looking for a new recruit after the sale of Belgian international midfielder Gaby Mudingayi to Bologna earlier in the summer.
Milan have now let Alberto Paloschi, Wily Aubameyang, Massimo Oddo and Brocchi go within the last 48 hours.
