Emmanuel Adebayor has passed a medical and will move to Manchester City once his work permit is approved.
The Togo striker, who has spent three-and-a-half seasons at Arsenal, is believed to be valued at £25m.
The 25-year-old, who scored 16 times for the Gunners last season, has also been linked to AC Milan and Chelsea.
City boss Mark Hughes said as Carlos Tevez was unveiled: “There have been discussions and possibly a deal to be done but nothing has been concluded.”
Speaking at the press conference to announce the signing of the former Manchester United striker, Hughes admitted that there could be more arrivals at the big-spending club before the start of the season.
“It may well be that opportunities will present themselves. We still have areas we want to strengthen,” he said.
City are intent on building a new-look attack and as well as Tevez have also added Paraguayan Roque Santa Cruz to their ranks this summer, having signed Craig Bellamy last season.
