Didi Hamann hopes to welcome more new signings to Manchester City this summer.
The German midfielder said: "Pre-season is always an exciting time of the year. A few players come in and others go.
"We've had a change of management as well and everybody wants to battle for a place. If we get a few more players in, that will increase the battle.
"Last season was a big improvement on the season before but we probably had the chance to finish in the top six or seven until April.
"But with a few new players we hope we can improve again from last season and I think everybody will be happy."
