Michel Platini says Fifa must change if it is to regain any level of credibility after Sepp Blatter was re-elected as the organisation's president on Friday.

The 79-year-old faced competition from Prince Ali of Jordan, but polled 133 votes to his rival's 73, which saw the challenger withdraw rather than enforce a second round of voting.

Blatter will now remain in charge for a further four years, but is under pressure to stand down after Fifa became embroiled in two serious criminal investigations earlier this week

Uefa president Platini said: "I am proud that Uefa has defended and supported a movement for change at Fifa. Change which in my opinion is crucial if this organisation is to regain its credibility.

"I congratulate my friend Prince Ali for his admirable campaign and I take the opportunity to thank all the national associations who supported him."

US authorities arrested seven Fifa officials in Zurich on Wednesday after 14 senior executives were indicted on suspicion of corruption and bribery.

Swiss officials later launched their own inquiry into the bidding process for the 2018 and 2022 World Cups.
