Tuchel also says he wants to keep

at Stamford Bridge. Broja was on loan at Southampton last season and West Ham wants to sign him permanently this summer.

"I don't expect him to leave,"

Tuchel told a news conference.

"We are aware of interest and offers, which just tells us there is a lot of potentials, and the owners and i will take this decision together in the end, also with the player.

"Right now when he arrived, it's clear he's trying to impress and is just trying to become a Chelsea player as soon as possible.

"After his loan at Southampton, the situation was very clear for him to take the next step, to show his improvement and make an impression in pre-season.

"Unfortunately he injured himself and of course, there is a lot of noise going on because there are offers and interest in him. Let's see how this goes but I'm pretty calm about it because we know the situation and we have a contract.”

has signed Raheem Sterling and Kalidou Koulibaly this summer and Tuchel says he would like a couple more signings. Chelsea at the moment is in negotiating with Sevilla over the transfer of defender

.

"I have a figure and I think we need a couple more players in to improve the squad,"

he added.

"We were third last season and there was a gap between us, Manchester City, and Liverpool.

"In general if you want to fight, even for the same position, you need to improve. You can never stand still because if you stand still then other teams will overtake you.

"Given the situation that we even lost players, it's common sense for me that we need to bring new quality to the team to maintain our level.

"It's always the dream of every manager that you find players in the same league and who can adapt maybe quicker than other players, but it's also a very individual process.

"Of course, we see that Raheem knows many players from the national team and he is very familiar with the habits of English clubs so this is very nice to see.

"For Kalidou, it's a big help that we have some French guys, that we have Edou [Mendy] his team-mate in the national team and of course Jorginho who is a big help from Napoli to make this process faster.

"Both of them should be huge players for us and that's why we need to speed things up."
