Berbatov, 27, signed a four-year contract with United after Spurs agreed to a $55 million fee for his transfer. Earlier in the day, City had reached an agreement on a $60 million fee for the Bulgarian international, who had his heart set on signing with United. But United matched the offer and threw in 20-year-old striker Fraizer Campbell on loan for the 2008-09 season. With an hour to go before the Monday midnight deadline, United had its man.
Berbatov scored 27 goals in 70 games for Spurs after arriving from German club Bayer Leverkusen. He is considered one of the most versatile forwards in the English Premier League and joins a United strike force that includes Cristiano Ronaldo, Wayne Rooney and Carlos Tevez.
Just minutes before the end of the transfer window, City confirmed the signing of Robinho for a British record $58.5 million transfer.
Chelsea was also in the running for Robinho, whom Real Madrid coach Bernd Schuster left out of the squad for Real's last two matches
The signing followed news earlier on Monday that City had agreed to a takeover by Abu Dhabi United Group for Development and Investment from the club's owner, former Thai premier Thaksin Shinawatra, for $360 million.
