Arsenal boss Arsene Wenger says he'll be careful with the signings he makes this summer.

Wenger accepts he must buy during the summer transfer market.

"The last three months is a springboard for next season. We have to transfer that belief into the start of next season, we need stability and to strengthen. Is it spending a lot on one player or buying many players?

"We want additions but we want to keep the structure and spirit and quality of the team. But let's not forget there are many clubs with big money and maybe not enough talent to strengthen all the teams. But we will go out in a proactive way."
