Johansson told a news conference that the formation of such a private league and excessive commercialisation was a threat to the sport's future.
"We are not looking for a compromise. We are not going to co-operate with a private league," he said.
"There is a risk that the soul of football...is getting lost and if something like this should happen we will all suffer."
Johansson, visiting Turkey for the 75th anniversary celebrations of the Turkish Football Federation, said European clubs generally shared these concerns and were open to proposals from UEFA.
"We are not nervous at all. Even the clubs concerned are asking us for a solution...I think we have the majority behind us," he said.
"If they are so interested, why have they not signed for this tremendous amount of money? Because they are clever people and they want to see the alternatives."
The UEFA head said a task force would present a proposal on the future format of European competitions to its executive committee early in October. The committee is meeting in Lisbon on October 6-7 and a package of measures, designed to take effect in 2000, is expected to be ready by the end of the year.
Among measures under consideration are the re-distribution of finance and the possibility of wild cards for major clubs in the Champions League.
UEFA has also indicated that it might merge the UEFA Cup and Cup Winners' Cup competitions.
The task force was working in co-operation with five major clubs, all former European champions - Juventus, Liverpool, Bayern Munich, Ajax Amsterdam and Olympique Marseille.
Johansson said earlier any clubs attracted by the Super League project which signed up with organisers Media Partners before UEFA presented their new plans would automatically exclude themselves from the UEFA statutes.
He also said UEFA had the ability to use sanctions against players and clubs if a breakaway takes place, but hoped to avert such a situation.
"The (sanctions) tool is there, but we should not go in that direction...I avoid making threats and thinking that we can't win the game. We are here to win the game."
UEFA's stance on sanctioning players, or clubs, who joined any breakaway league would likely be rigorously challenged by the European Union in Brussels who would certainly challenge UEFA on grounds of restrictive trade practices.
The Super League project revived concerns about the amount of matches which clubs were required to play and the broadcasting of matches on pay-per-view television - a move which UEFA would oppose unless it found wide public support.
"Our matches should be shown all over the place on free television...I doubt that we will go for pay-for-view," he said.
"People on the streets, the spectators, the fans, the clubs, all are against a break-up of a few from the football family," he said.
Asked about Manchester United's agreement to a $1 billion take-over by Rupert Murdoch's BSkyB, Johansson said that the views of local people in England were more important than his opinions.
But he repeated his concerns about commercialisation interfering with the "sporting criteria" at football clubs.
"It is when they interfere in the sporting criteria that I get worried...Otherwise I am not here to criticise Mr Murdoch, I think he knows what he is doing," Johansson said.
