Nemanja Vidic was greeted with great enthusiasm when he signed for Inter in the summer, but so far his spell at the club has been far from ideal.
The Serbian star decided to leave Manchester United when his contract expired and Inter were more than happy to snap him up, hoping he could solidify their defence.
But this season, Inter have looked suspect at the back and from his debut sending off onwards Vidic has looked out of sorts.
Vidic flicked on a long throw into the box and ball fell to Callejon, who produced an excellent finish. While not a glaring error, Vidic will feel he should have dealt with the ball better and he was dealt with harshly by the Italian press, who labelled him 'a disaster'.
Callejon found the net again in a 2-2 draw with the whole Inter defence looking static as he nipped in behind to volley home. Vidic seemed to be playing Callejon onside.
However, Vidic did do very well to block a goal-bound Gonzalo Higuain effort and he went close to scoring with a header.
While Inter rallied to grab the draw, which may have prevented coach Walter Mazzarri from being sacked, Vidic still looks unsettled and hasn't made his mark yet.
