Horndean finished this season’s National League division two south campaign in fifth place after forfeiting their final two matches.
The Deans’ once-promising push for glory tailed off with a whimper, as they suffered without influential players during key matches.
Although forfeiting the last games against Exeter and Wessex has been deemed an embarrassing debacle, winning both encounters would only have seen the Deans finish fourth.
The acquisition of Cyprus youth international Konstantinos Yiannakkos and keeping proficient setter Leandros Tsikras gives the Deans a lift for next season.
Ssemuwemba said: ‘The true measure of any team is consistency and in this sense we failed to see our season over the line.
‘Injuries always posed a threat and having a small squad also meant it was difficult to have adequate replacements.
‘But the fact is we had a few players who were not dedicated to a cause and that led to the slip from league contenders to mid-table finishers.
‘As a coach you are always looking for a sign you are moving in the right direction and this disappointment has made us even more determined not to rest on our laurels.
‘We want to make sure we put right what went wrong during this season. We owe that to ourselves and the fans.
‘My aim is to take this side to division one and I’m confident that’s achievable.
‘This time, I’m going to try to get players who are willing to help us achieve this ambition.
‘There is no underestimating the impact a unsuccessful end to this season is going to have on the mood of the squad over the summer.
‘But I hope we can put the inconsistencies of this season behind us and assemble a decent team that will provide fans with a true crescendo, come next season.’
Meanwhile, two of the Deans top players, Norwegian ace Haakon Lie and Greek libero Adamantios Xanthoudidis, have both left.
They have finished their studies at the University of Portsmouth and will be moving on.
