You might have thought former Chelsea winger Pat Nevin would have a pathological loathing of full-backs, but he is the latest member of the Bosingwa fan club, as he explains in this week's column.

Tomorrow night's trip to Cluj really is a voyage into the unknown. It used to happen quite regularly in the Champions League that you would come up against a side you new little or absolutely nothing about, however this is as close as you generally get to that feeling in the group stages these days.

Cluj are of course from Transylvania, which of course has only one set of connotations for anyone brought up in the UK. Immediately you think of blood-curdling horrifying screams, of frightening sights that once seen are etched on the mind forever and if we are to be absolutely honest a love of kitsch tackiness on film that we Brits have always fallen for. However enough chat about the Cheeky Girls and back to the football.

Clearly the Romanians will not be taken lightly following their result against Roma. Their Italian coach Trombetta will have particularly enjoyed the shock result of Matchday One but he now knows his cover is blown and that no one, including last year's beaten finalists, will arrive taking anything for granted or being over confident.

One player full of confidence for Chelsea following his first goal for the club is José Bosingwa. While all eyes were on Deco, the Portuguese right full back quietly settled in and has not had a bad outing since his debut against Portsmouth in the first game of the season.

Chelsea have had a very long list of players in that position over the past few years, but none has really been able to make it his own. That uncertainty is over now and he already looks to me like a shoe-in for the PFA Team of the Year at the end of the season.

He represents the winger's nightmare in that he likes a tackle but also wants to spend more time attacking down the flank than defending, hence the opponents' wide players spend more time chasing him and usually only receive the ball about 60 or 70 yards deeper than they would prefer. This is of course no fluke, Scolari knows that few teams will allow their wide midfielders to let a full back run into space unchallenged, after all look at what happened against Stoke when he was not followed.

There are some wide men who will not track back but they are the sainted and lucky few such as Ronaldinho and Messi. Most full backs curtail their attacking instincts in deference to these world stars but the megastars are the exceptions that prove the rule.

Bosingwa is one of the best raiders from deep in the modern game, because it is not just pace, it is also skill he uses to get round the back of opposition defences. Very few full backs have 'a trick', but he has more than one. I suspect watching him that he has played as a winger at some point even if it was just as a kid.

Last week I was actually looking forward to a battle between him and Ronaldo, but the Man United player played mostly on the other side when he came on, so that particular spectacle will have to wait for another day. It had actually been a problem for Chelsea as Ashley Cole always struck me as getting the better of Ronaldo and so he preferred to switch to the other side when he played against the Blues.

In the Champions League final, remember we had to sacrifice the talents of Michael Essien in the midfield to play at right back to match up to the Portuguese winger.

That will not happen again with Bosingwa and maybe Chelsea will be one team who can nullify his considerable talents this time round. This is important because without Ronaldo playing well United are a far less impressive outfit as we have seen already this season.

I really do think that with the introduction of Bosingwa, and everyone else fit, this is the strongest defence Chelsea have had for…well forever really. With that in mind we should be very hard to beat even on the occasions when the team has an off day middle to front.

The upside of having José and Ashley Cole bombing forward is that they will add something unexpected even when the usual suspects are well marked and struggling to find space.

When Chelsea are heading home from Romania I will be watching Everton and Aston Villa in the Uefa Cup. Villa are next up on Sunday and for me they have been the surprise package of the season. Everyone will remember the high-scoring drama against Martin O'Neill's side at the Bridge last season so this one will be a cracker considering their improvement. They will have to be very good going forward however if our defence remains intact.

Last week's question certainly had you thinking. I asked which players who went on to become Chelsea legends had played for Wimbledon in the FA Cup Final win against Liverpool in 1988. Well there was some debate on what constitutes a legend, but for the purposes of the quiz I am taking it that anyone who played for the Blues was a Chelsea legend to one degree or another…yes I know it is pretty weak, I know I shouldn't throw that legend word around too loosely.

Anyway there were four, Vinnie Jones, Dennis Wise, Dave Beasant and the one that most forgot was Terry Phelan. One woman who didn't forget was this week's lucky winner Celia Mindelsohn.
