What is it like to be a young player making Stamford Bridge sit up and take notice? Who better to ask than Pat Nevin who posts this week's column from Porto.

Obviously there are many things to be happy about with Chelsea at the moment. The run of clean sheets and the incredible winning streak at home are worthy of a good deal of celebration.

Being top of the league with a bit of breathing space isn't too shabby either and there is of the course the little matter of the position in the Champions League group that also brings a contented smile to those of us with blue blood. The idea of going to Porto this week with the pressure well and truly off is just the sort of thing that Carlo Ancelotti's dreams are made of at this time of the season.

The demolition of Wolves at the weekend was also pretty special and doing it without the 'core' of the team in Lampard, Ballack and Drogba was just rubbing salt in the wounds of Mick McCarthy's men. More than that it was also an eye opener and a warning shot to every other team in the Premier League that thinks Chelsea are over dependent on any one player or even a group of players.

Because of his popularity, the goals from Michael Essien were also joyous moments at the weekend, but I would argue that it was even more poignant when Joe Cole knocked in the fourth goal in the second half.

His first for more than a year will have a great effect on him. When you have had a long-term injury, it is like a long distance steeplechase, there are a number of psychological barriers you have to overcome before you are truly back. With that goal Joe didn't only clear the last hurdle but he broke the tape at the end of the race…welcome back Joe, you have been missed.

For all these wonderful moments, there was one that stood out for me even more. Young Gael Kakuta came on to the pitch as substitute and received the ball in the opposition penalty box. He shaped up to play in a left-foot cross but then sold an outrageous dummy and cut inside before smashing it into the side netting.

It was a moment of such precocious skill performed at such pace that it had the watching fans (and a few ex players) gasping at the spectacle.

The rest of the youngsters looked just as impressive and though there is a lot to learn and a long way to go, as they say in the trade, he has a chance, a big chance.

There is something very special about that moment when a new young player steps onto the field and immediately does something different. In many ways it is even more exciting than when a new multi-million pound high profile international signing does the same, because from the youngster there isn't the same level of expectation.

I can tell you from experience, albeit a good few years ago, as a youngster breaking through at Chelsea, the frisson of excitement that is generated in the stands is immediately transferred into confidence for the young player. It has the same effect as being given a shot of pure adrenalin. The more the fans back him, the more chance he has of succeeding.

There were of course particular pressures on Kakuta because of the peculiar nature of his signing and the media furore surrounding it. If ever a player looked blissfully unconcerned by the hype and the headlines however, it was he during that brief appearance on Saturday. I really hope that those exciting moments were just a taster for great things to come.

Also in his favour is the fact that there might be a few more first team opportunities in the weeks to come, considering the injuries and the African Nations Cup absences we expect in January. It also helps any forward coming into a team if he is surrounded by quality players who are playing well, winning and spending most of the time in the opposition's half.

I am in Porto right now, once again covering the game for BBC Radio 5 Live and I must say I am rather looking forward to it. With the pressure off it once again gives the gaffer a chance to try a few different things and a few different players. Whether young Gael gets another chance remains to be seen but it will certainly be another big step in the learning process when he gets his European debut.

His breakthrough also gives hope and belief to any other young players trying to break into what is a world-class team; it is a difficult task but not an impossible one. One player who I hope has the right reaction is Daniel Sturridge. Nothing should spur him on more than the knowledge that if you do have the right attitude, the belief and the work ethic, success awaits. In simple terms it is up to him.

Last week I asked how many times the club badge had been changed in the club's history; the answer is that it has been changed four times because the club has had five official badges. The winner picked from all the correct answers - if you said simply the club has had five badges you were considered correct - was Ashley Manton from Ontario in Canada and the video of last season will be on its way.

This week when I have been talking about youngsters breaking through, could you tell me who is the youngest player ever to play a league game for Chelsea? Answers as ever to pat.nevin@chelseafc.com and the winner picked at random from the correct answers will receive a DVD of the FA Cup Final win over Everton. Good luck and good luck to the team in Porto.
