Arsene Wenger is pleased with the way Sol Campbell has settled back in to Premier League life with Arsenal.
The Gunners boss caused a major shock in January by agreeing a deal to bring the veteran former Tottenham and England back to the Emirates Stadium but Campbell has performed well in the absence of the injured William Gallas.
He has already made four appearances for the Gunners and scored in last month's Champions League first leg clash with FC Porto.
Wenger said: "It was unexpected that Sol would play so many games, but it is also good because I think it was the right decision to bring him back. Sol is a guy who gives everything when he is on the pitch.
"Can his body still take two or three games in a week? Who knows. But we have a good mixture with him and Silvestre because he is also a player who gives everything on the pitch, so we can rotate them.
"The only problem is that when you play with two left-footed players sometimes Vermaelen is not always in his best position.
''Sol wants to win and he can spread that through the team and give advice. We want to win this game (against Porto) but we also need to be patient maybe and it is important to keep your head.
"He gives us a good mixture, it is not only him, but there is a good blend of youth and experience."
