Full Backs:
Ola Aina (Right Back)
After a fine loan spell with Hull City, Chelsea's budding youngster, Ola Aina returned to the London, put a pen on a new contract and then again left England to Italy as he joined Seria A outfit Torino in search of first-team experience.
Aina, 21, who normally plies his trade as a right back, has earned the reputation of a fine right back and in future, could achieve a place in the Blues' squad. High physical presence, great agility, and brimful stamina; Nigerian does possess this all and becomes a loanee to keep eye on.
Jonny Castro (Left Back)
Jonathan Castro Otto, on loan from Atlético Madrid, is getting considered as one of the best moves of Wolverhampton Wanderers in the transfer window in the recent years as the 24-year-old left back outlined his enormous talent number of times.
World Cup winner with France Lucas Hernández emergence and still Filipe Luis becoming the first choice for the Madrid outfit further restricted first-team opportunities of the Spaniard and loan move to the Premier League's new boys, Wolves, made a sense.
He might not attract the eyes for what he does further in the field but in terms of minimizing the intensity of threats, man to man covering and covering and game sense, the fullback is extremely well. Castro has already started to impress at Molineux Stadium as he produced stunning statistics of 3.3 tackles, 2 interceptions and 1.8 clearances per game. Over the last couple of campaigns, it's hard to find out any big errors or poor showings he made and in a way, he has arguably earned the reputation of 'Mr. Reliable'.
