The Hammers midfielder is relishing the chance to come up against Guardiola's Manchester City side in the Emirates FA Cup Third Round tie and feels his team-mates will want to put on a show in front of the televised cameras at London Stadium.
Obiang grew up watching the famous Barcelona side that Pep put together and feels he will be a fantastic addition to the Premier League.
But the 24-year-old is determined to have a good run in the FA Cup and after visiting Wembley earlier in the season, he would love to help his team go all the way in the competition and bring some silverware back to the east London Club.
Obiang said: “I followed Pep when he played for Barcelona and then he played in Italy. It is easy to follow him because he is such a big manager and everyone knows about him.
“He lives and eats football! I am happy that he is a Spanish manager and I was pleased to see him come into the Premier League because he did such a good job managing in Spain and Germany.
“I have never played against him before and when I played against Barcelona he was manager of Bayern Munich.
“I went to Wembley to watch the recent friendly between England and Spain and thought it was amazing there.
“I would love to play there and hopefully this season could be the year we get to the final!
“This is the only cup competition we are left in and we want to play a good game on Friday. We seem to play well against the big teams and last season we had a lot of difficult games but we managed to reach the quarter-finals.
“I think we are a lot better this season and now we are trying to change something. If we play well in this game I think we could go on to win the cup.”

Pedro Obiang
Obiang has been quietly going about his business at the heart of the West Ham midfield, but he has been one of the star performers this season.
With Cheikhou Kouyate departing for the Africa Cup of Nations, Obiang knows there will be even more responsibility on his shoulders, but he welcomes the pressure and says it would be a dream way for him to start 2017 if he can finally score his first goal for the Club.
Obiang added; “At the moment I need to continue this kind of form and I want to get even better. I need to score my first goal for West Ham because that it is important for any player.
“I have come close but that is not good enough! I want to get on the scoresheet. Once I score my first goal hopefully I can score a lot more.
“I don't feel any more pressure with Cheikhou going away, but maybe I am lucky that I will get the chance to play. Last season I was on the bench and I needed to be ready every time I was called upon. Now I have my chance and I want to make the most of it.
“You need to feel confident when you are playing. It is not easy when you are not in the side, but when you are playing everything changes and you feel the confidence.
“I set the bar quite high and this is good for the mentality and all the players need this.
“When Cheikhou comes back he will make the team even stronger, but now we have to cope without him. It was the same last season when Manuel Lanzini was missing through injury and we needed to be stronger together and continue in the league.”
