The World Championships were a disappointment for Great Britain, with individuals and the team as a whole failing to perform.

They should have beaten the Netherlands in the quarter-finals - that 57-53 defeat cost them dearly and they eventually finished fifth.

The Netherlands were a limited team but they knew exactly what their roles were within the team and their one world-class player Koen Jansens was good enough to take them through.

Simon Munn struggled with injury during the tournament

The GB players had more talent but in terms of motivation, the way they were coached and their approach to the games, the Netherlands were far superior.

I said before the tournament that GB needed five players to score solidly but that didn't happen.

Apart from Jon Pollock, Simon Munn, Terry Bywater and Colin Price, the rest only shot 23% from two-point range, which isn't good enough.

There is no quick-fix solution. The players were the best on offer but they didn't perform. I think they have been under-performing for two or three years and this tournament was the one where they were finally found out.

However, their under-performance coincides with a time where some of their other rivals are also in a period of change.

The overall standard of the tournament was poor and only the Netherlands, who finished fourth, could hold their heads up high.

Although he will no longer be coaching the team, I think it is good that Dave Titmuss is staying involved as performance director.

"I think Great Britain have got to look to consolidate"

He is so professional and has a huge amount of coaching experience and is the best man for the job.

In his six-year reign I think his decision-making was very good but his last decision, namely the one to leave the coaching job, maybe came one year too late.

I think the GB Wheelchair Basketball Association now have to choose the best person for the job, whether that is someone from here or abroad.

There aren't too many outstanding candidates but I think Gert van der Linden from Holland would be a strong one if they are looking abroad.

He was a great player and coached the Netherlands superbly at these World Championships but I don't know whether he is available.

Unfortunately, whoever takes over from Dave will inherit one big problem in that the pool of players he had to work with was small.

He didn't have a big turnover of players and inevitably there comes a time where players have heard it all before from the coach and vice versa.

Ade Orogbemi was one of those who played in the Netherlands

I don't know whether Dave's decision will signal the end of the road for some of the more experienced players but it is a crucial time for wheelchair basketball in Britain.

I think we need to look at our systems and look at the way other countries do it and maybe follow them a bit more closely.

We haven't got the depth in the guard position that we used to have so it could be time for changes there.

Overall, I think Great Britain have got to look to consolidate.

The priority will be getting to the semi-finals at next year's European Championships to reach the Paralympics.

At world level, Canada and Australia may be out of reach in the short-term.
