Russian midfielder Marat Izmailov has signed for Porto from Sporting Lisbon for an undisclosed fee.
Izmailov inked a two-and-half-year contract with the Portuguese champions in a deal that sees full-back Miguel Lopes move in the opposite direction.
With Tottenham chasing Joao Moutinho, coach Vitor Pereira did not want to leave his side short of numbers in midfield and swooped for the Russian international.
The 30-year-old said Porto’s history was a big factor behind him deciding to make the move from their Liga Sagres rivals.
“I have spent almost six years in this country and Porto have won the title practically every year,” Izmailov told reporters.
“Everybody knows that Porto are a great team with a big, strong structure. Their results are better than those of any other Portuguese club.
“I hope to win trophies at Porto and to progress as a player and person.”
Porto president Pinto da Costa feels Izmailov will add some depth to their squad.
“Izmailov will strengthen our squad. Luckily, we have a strong team, but it’s not just about 11 players. I think Marat will get a feel for our playing style and will appreciate our club spirit,” he said.
Meanwhile, right-sided defender Lopes has made the move in the other direction, agreeing a two-year deal at Estadio Jose Alvalade.
