I've got his fight against Michael Hunter on tape but don't remember anything about him to be honest. Looking at his record Simpson can beat him.
It is only possible to hold one of those belts at a time, the undisputed European champion is the EBU holder. EBU-EE means external European Union(so in Europe just not the EU), the fighters do have to be European though and it's mainly contested by fighters from the former USSR. It seems every few weeks people confuse the EBU and the EU titles...... The advantage of holding the EU title is like that of holding an International/Intercontinental belt, it helps move you up the rankings and often if you make several defences you will become mandatory. However unlike International/Intercontinental belts, the EU belt has its own rankings and most of the ranked fighter are already ranked by the EBU, you just usually get a few extra fighters at the bottom of the rankings who aren't good enough to be ranked for the full European title.
i was bored earlier and emailed the EBU and they confirmed you vcould only hold one belt.i dont think they seen the funny side ... but you have to admit it would be brilliant .
