Inter Milan president Erick Thohir says they'll be busy this summer market.

Inter coach Roberto Mancini is insisting on a major overhaul.

"We are working very hard to form a strong team," the patron told Sky Sport Italia.

"We need to support Roberto Mancini. Mauro Icardi is one of the future stars for us, that's why we want to keep the team and build big things together with Mancini.

"It will be a good summer, as it was before. We brought important players over the last few transfer sessions, but the most important thing is not who we bring, it's becoming a solid team. That's important."
