But Coleman admits he will have to negotiate a few more transfer windows before he will have a chance of restoring the club to its former glories.
Coleman told the club's website: "We hope there'll be other signings before the start of the season. We might lose one or two, that's the way football is, but it's been very fruitful so far.
"Like I said, there's been a lot of hard work but we can't just sit back and think that's enough. We've got three new players and we know where we want to be and how we want to strengthen our squad."
Coleman added: "It's not going to take one transfer window to get to where we want to be, it will probably take two or three, but we are very happy with the three players we have got so far and we hope to have some more in before August 9."
