The Swede completed a permanent move to Elland Road to the delight of the Leeds fans, having initially joined the club on loan from Italian side Torino.
Playing at centre-back, the 26 year old has established himself as one of the best defenders in the Championship. Having being named in the EFL team of the year for last season.
One thing that stands out stats wise for the defender is that he averages 10.2 clearances per match, showing he’s not afraid to smash it into row Z when needed. Compare that to Reading’s best, Liam Moore, who’s down at 6.5, with Paul McShane at 4.1
Furthermore, with the former Torino man making 1.2 blocks per game, you can expect Jansson to put his body on the line for his side and make life difficult for the Reading strikers.
The Spaniard is the new signing at Elland Road having completed a move from Spanish side SD Huesca in the summer.
Since arriving in England, Saiz hasn't look back having scored six goals in 11 appearances in all competitions so far this season. Including a hat-trick on his debut against Port Vale
But it’s not just scoring goals that catches the eye with Saiz, as he’s also shown he’s able to provide as well. The forward averages 2.4 key passes per game, meaning you’ve got to keep him quiet inside and outside the box as well. That creativity tops any Reading player, including Sone Aluko (2.2), while Jon Dadi Bodvarsson is at just 0.6.
If Reading are to come away from West Yorkshire with a decent result then they will need to make sure Saiz doesn't start pulling the strings in his sides favour or it could be a long afternoon down at Elland Road.
The final player that Reading fans should keep an eye on is Pierrie-Michel Lasogga.
Like Saiz, Lasogga is the new signing at Elland Road having signed from German side Hamburg on a season-long loan.
The striker hasn't looked back since completing a move to Leeds, having scored three goals in five Championship games with two of those coming against Burton Albion on his debut.
As a result his offensive stats for this current campaign have been very impressive with the centre-forward averaging 3.6 shots per game. Which is over twice as much as what Reading striker Jón Dadi Bödvarsson has so far managed to average.
With Saiz and Lasogga having the potential to cause major problems, the likes of Liam Moore and Paul McShane will have some task at stopping this two talented players from dominating the game.
