Alfie Mawson

Alfie Mawson completed a transfer from Barnsley last summer and has not looked backed since making his Premier League debut against Watford last season.

Having managed to keep a clean-sheet on his debut. The centre-back went on to make 27 appearances scoring four goals, helping his side avoid relegation.

He also managed to average one tackle and 1.1 interceptions per game, which perhaps showed he wasn't quite ready for the Premier League.

However, Mawson’s performances for England at this summers Under 21 European Championships were nothing short of sensational, helping his country to the semi--finals of the tournament.

What’s even more remarkable though is that Swansea paid just £5 million for his services, a bargain compared to what clubs charge for their players in the current transfer market.

Additionally, according to Squawka, Mawson won 63% of his duels last season meaning a fascinating aerial battle could be in store between himself and Jón Dadi Bödvarsson.

Renato Sanches

The Portuguese international is the new signing at Swansea having signed on loan from German Champions Bayern Munich in the summer.

Playing as a defensive midfielder, Sanches has been tipped to be a future star of world football. With the 20 year old being known for his aggressive style of play and being able to carry the ball from one end of the pitch to another in the blink of an eye with his pace and his technique.

However, Sanches hasn't quite kick started his career at Bayern Munich since completing his £35 million move from Benfica in July 2016.

Last season, the talented youngster made a total of 25 appearances in all competitions, making an average of 0.5 tackles per game and 0.6 interceptions per game.

Secondly, with a passing accuracy of 88% during his time at Bayern Munich last season. The likes of Joey Van Den Berg will need to make sure that Sanches doesn't start pulling the strings in his sides favour.

Tammy Abraham

The final player that Reading fans should keep an eye on is Tammy Abraham.

Abraham should be a familiar name to Reading fans, having scored twice against the Royals in the thrilling 3-2 win over Bristol City at Aston Gate in the last campaign.

Last season, Abraham scored 26 goals in 48 appearances in all competitions finishing behind the likes of Glenn Murray and Chris Wood in the goal-scoring charts. That’s despite having a shooting accuracy of 45%.

The striker has made a decent start to life at Swansea having scored two goals in six appearances in all competitions so far this season.

Abraham is a real fox in the box, a centre-forward that punish any defence if given the time and space.

If Reading are to progress in the cup the Royals defence will need close down Abraham and stop him from getting shots away on Vito Mannone’s goal.
