Arsenal defender Sol Campbell says he is impressed with the makeshift defence the Gunners have at the moment.
Campbell watched from the bench as Arsenal managed to hold out Juventus for a 0-0 draw in the second leg, which put them through to the Champions League semi-finals, after beating the Italians 2-0 in the first leg.
The England star has admired the way the back four have played this season, managing to record eight clean sheets.
"It's nice because whoever has come in has done well, so that's fantastic. You need that as a team, there's either been a few changes or a few injuries and things like that and you need to keep the performances up. It's brilliant, I'm happy," Campbell told Sky Sports News.
Campbell also revealed that he is fit and ready to play for Arsenal again, after overcoming injuries.
"When the manager picks me and wants me to play, I'm ready. It's all there now, so I'm just waiting for my chance. I want to get a few games under my belt, so we'll have to see what happens for the rest of the season."
