Cardiff City have confirmed the four signings dai-sport have been talking about for some time.

Twins Jack and Paul McKay, Ciaron Brown and Ogo Obi have all been on trial with the Bluebirds and have now signed under-23 development contracts.

The McKays are 21-years-old, 6ft 2ins tall and the sons of football agent Willie McKay.

They have signed contracts through to 2020 and are likely to be in the Bluebirds development team for their under-23 match against Coventry City away next Monday.

Both are Scottish and have had spells with Doncaster Rovers and Leeds United. Jack is a striker, while Paul plays at the heart of defence.

Nigerian-born striker Obi, aged 19, attracted interest from Liverpool and Arsenal, while he had a trial at Manchester United when Louis Van Gaal was manager.

He was released by Watford at the end of last season and has been playing for Hemel Hempstead Town. Obi has signed for Cardiff until the end of this season.

Brown, 20, is a centre-half or left-back. A number of Championship clubs have been checking on the tall, combative Brown, who spent time at Sheffield Wednesday.

He joins Cardiff City from National League South side Wealdstone after completing a trial with the Bluebirds. Brown made 66 first team appearances for the Stones, scoring three times. He has signed a two-and-a-half-year deal with Cardiff City.

Cardiff’s development team travel to Coventry City for their Development League match at the Alan Higgs Centre on Monday (January 29, 1.30pm), while they then play two home fixtures in four days.

Watford play at Cardiff International Sports Campus, opposite Cardiff City Stadium, in a League Cup match on Thursday, February 1 (1pm), while Queens Park Rangers visit the Cardiff Campus on Monday, February 5 (2pm).
