After the first leg of the Supercopa ended in a 2-2 draw at the Bernabeu, Guardiola's men remain in a strong position to lift the first silverware of the new season in Spain. However, the Barcelona boss believes his team has a great deal of work still to do, despite the Catalan club recently landing long-time transfer target Cesc Fabregas.
Pep Guardiola has suggested Real Madrid are better than his Barcelona team as both clubs prepare to do battle in the second leg of the Supercopa.
"In the first leg, Madrid were better, in these three days we have improved some things, but I believe they are still better," he said.
"That is the feeling I have, but every match is a story. If the return leg were in two weeks, it would be different. We will have to play better than we did at the Santiago Bernabeu to win the Supercopa.
"We will have to play with the kind of speed we could not put in our game the other day. Three days have passed, we have trained really well."
Meanwhile, Guardiola confirmed he will give Fabregas his first run in a Barcelona jersey after the former Arsenal skipper joined the Spanish giants on Monday.

"He has trained very well, a lot of time alone, and also some bits with the team. He will surely be in the squad, but [Wednesday] we will see if he will play the whole 90 minutes or not."
