Celtic still need a centre-back and Brendan Rodgers ought to consider the 31-year-old.
Celtic could and should still bring in a centre-back this summer.
With Dedryck Boyata ruled out for three months, Celtic boss Brendan Rodgers only has two proven options in the form of Erik Sviatchenko and Jozo Simunovic.
Steven Caulker has been linked, but should Rodgers also consider a switch for Nottingham Forest defender Matt Mills?

According to The Daily Record, ex-Hoops boss Neil Lennon was a “big admirer” of the then-Leicester City man, whom he tried to sign on loan in 2012.
Of course, that is not to say that Mills is the same player but 70 Championship appearances over the past two seasons should illustrate that the 31-year-old still has something to offer.
England’s second tier is a tougher division than the Scottish Premiership and his longevity there might suggest that he could cut it in Scotland’s top flight.
He is out of contract with the Reds next summer and the Celtic boss could potentially pick him up for relatively cheap.
