Lazio's change of tactics at halftime was very odd.
In the first half, they were absolutely strolling it: a goal up and keeping comfortable possession for extended periods.
Then they go and drop Cana back from midfield to defence to make it a back five.
That meant that it was much harder for them to keep the ball or to put any pressure on Palermo high up the pitch.
Lazio went deeper and deeper and it wasn't a surprise when they conceded.
Petkovic does seem to have a habit of being unnecessarily cautious when playing away from home.
I've been banging on about how good Lazio's midfield has been this season, allowing them to do very well despite their defence just being okay. Well, today you could see what happens when the midfield doesn't give good protection and the defence actually has to do the bulk of the defensive work.
