Everton boss Ronald Koeman has assured fans there won't be any down time for him during the summer market.

Koeman says his mobile phone will be by his side as he hopes to add “productivity" for Everton over the summer.

He told the club website: “Everyone knows we would like to do some good [transfer] business.

“I will have my mobile phone close to me so if there is anything we need to discuss or I need to get a flight, I am available.

“A clear objective will be to bring in players who will have more productivity. I expect that we can change that for next season. If we can do the business we want to do this summer, the team for next season will be really strong, I believe."
