Barcelona great Hristo Stoichkov insists tonight's Champions League final is wide open.
Stoichkov says Inter Milan are capable of upsetting Manchester City.
He told Sky Sport: "Two teams that had a great season. Inter had an incredible Champions League by hitting the final. City suffered during the season, but in the end managed to win every trophy so far.
"I want to congratulate (Javier) Zanetti and (Simone) Inzaghi for the work they have done. The world says City are favourites, but for me the only difference is Guardiola.
"He has more experience in similar matches. Sometimes, however, a substitution, a detail, is enough, which can make the difference."
