The English champions have made their final and shocking signing only a few hours before the close of the transfer market. With Diego Costa unable to make a last-hour switch to the club that sold him to Chelsea, instead, arrives a player whose name will confuse many supporters with the name of former Brazilian striker. The transfer period has been very frustrating for the North Londoners who lost nearly all their key targets to their rivals.

Antonio Conte's side had earmarked Romelu Lukaku to replace Diego Costa who had been rattled by the manager's text soon after the last season's glory.

The failure to land the Belgian striker, who instead signed with Manchester United, prompted Chelsea to settle for Alvaro Morata after also failing to lure Torrino's striker, Andrea Belotti to Stamford Bridge. The disappointing recruitment for the Blues never ended there as they also witnessed Liverpool hijack their bid for Ox-laid Alex Chamberlain. The transfer dramas intensified with the Everton midfielder, Ross Barkley changing his mind midway through his medical test against joining the defending champions.

Who excactly is Davide Zappacosta?

I'm sure that is the question that many Chelsea enthusiasts are asking after hearing the player's name for the first time and to learn that he's already part of the team.

The deadline deal for the 25-year old Italian will remind many soccer lovers about Davide Zappacosta's namesake David Luiz who signed at Chelsea for the second spell on the final day of the transfer in 2016.

With the signing Zappacosta, Chelsea will ease the frustration of failing to secure his former Torino teammate, Andrea Belotti.

In fact, it's Zappacosta who plays a fullback position who made countless crosses that the lethal Belotti converted into goals. The signing of the former Atlanta defender will offer Chelsea with the ideal back-up for Victor Moses in case of suspensions and injuries.

The defender who is well acquainted with the 3-4-3 formation is joining the German defender, Antonio Rudiger who also left the Serie A side, Roma earlier in the summer.

The Italian defender some times finds himself in the score sheet for his clubs as he makes his usual offensive moves, but he has never scored for his national side in his four appearances. Also, he had played for the Italy U21 where he never scored a goal in his seventeen caps.

Why is Conte interested in players from Italy?

It's clear that the Italian tactician is keen to play players who have had a stint in the Serie A. He first signed Marcos Alonso who's enjoying a successful period at Chelsea after exiting Fiorentina. The other players who have Serie A experience and have joined the Blues during Conte's tenure are Alvaro Morata, Antonio Rudiger and now Davide Zappacosta. Besides, the admiration that the Chelsea manager has for the Torino's attacker, Belotti is simply irresistible.

Maybe, because Conte's former side, Juventus also hailed from the same city.

The main reason why Conte prefers players from the league where he won the crown at Juventus before coaching his native national team could be because of their knowledge of his favorite 3-4-3 system of play. The question that many people will seek to find its answer in the near future is whether Davide Zappacosta can dislodge Victor Moses from the starting line-up.
