Manchester City are reportedly close to securing deals for Porto duo Eliaquim Mangala and Fernando for a combined fee of around £41m.
The Blues had tried to sign the pair in the January transfer window, but were thwarted when deals could not be completed in time.
However, The Telegraph claims that City's sporting director Txiki Begiristain has continued negotiations with the Portuguese giants with the pursuit of Mangala said to be closest to completion.
Fernando is also reported to be attracting interest from City, despite signing a new contract with Porto in February, with the fresh deal believed to be just a measure to preserve his transfer value.
The midfielder is thought to have a buy-out clause worth £25m, but is not expected to move for anything near that figure.
