Here are my recommeded ins after my first 3 seasons with Anzhi, and currently in 2015/16 season
Season 1
Walter Montillo from Cruzeiro, amazing for the first 2 seasons as a creative AM - £14M - will count as a foreign player.
Chidi Odiah from CSKA, decent cover for right back - £2.4M - Russian national
Along with good young Russian players
Season 2
Carlos Fierro from Chivas, one for the future but amazing at 19 with 34 goals in 33 games - £2.5M - foreign but you'll want to keep him for 5 years cause he'll gain russian citizenship when he's 23/24
Alan Dzagoev from CSKA Moscow, quality Russian AM or CM - £21.5M - Russian
Along with other decent players.
Season 3
Jan Vertongen from Ajax, quality Ball Playing Centreback - £10M - foreign
Vasily Berezutskiy from CSKA Moscow, best Russian CB you can get and experienced - £15M - Russian
If you get any of these players they will do really well for you. Get them as soon as you can is my advice.
Other players you should look at are:
Roman Pavlyuchenko from Tottenham - Russian
Diniyar Bilyaletdinov from Everton - Russian
Pavel Mamaev from CSKA Moscow - Russian
Tomas Necid from CSKA Moscow - becomes Russian in two or three years
Evgeny Makeev from Spartak Moscow - Russian
Cristian Ansaldi from Rubin - becomes Russian quickly
