Roma boss Jose Mourinho is once again turning to a familiar face as Nemanja Matic prepares to join him at the Stadio Olimpico.
The former Serbia international first signed for Mourinho at Chelsea and they were re-united in Manchester during Mourinho’s spell at Old Trafford.
The Portuguese manager has regularly turned to players he has previously managed and knows he can trust.
Going right back to his Porto days, Mourinho signed Maniche in 2002, who had worked with him during his brief spell at Benfica.
Maniche was an instrumental part of the Porto side which back-to-back league titles as well as the UEFA Cup and Champions League.
The pair were reunited again at Chelsea in the 2005-06 – where Maniche found a couple of his former Porto team-mates.
Following the sensational 2004 Champions League success with Porto, Mourinho had moved to Chelsea that same summer and brought with him two of his key defensive components in Ricardo Carvalho and Paulo Ferreira.
Goalkeeper Henrique Hilario was a Porto player during Mourinho’s time there but was mainly on loan away from the Estadio Dragao. He joined Chelsea at the start of the last full season of Mourinho’s first spell in 2006 and serious injuries to both first-choice Petr Cech and second-choice Carlo Cudicini, saw him play more matches than expected.
Despite regularly being linked with former players while at Inter, he didn’t sign anyone he had worked with before during his two-year spell.
Real Madrid came next and he immediately re-sign Carvalho. Mourinho also gave Lassana Diarra, who he managed at Chelsea and found at the Bernabeu, a key player.
In 2012-13, his final season with Los Blancos, he signed his former Chelsea stalwart Michael Essien on loan.
Mourinho returned to Chelsea that summer to find goalkeepers Petr Cech and Hilario, defenders John Terry and Ashley Cole and midfielders Frank Lampard and John Obi-Mikel from his first stint.
In his second campaign, he signed Matic for the first time and turned to Didier Drogba, who had served him so well when he first managed Chelsea.
During the first term of his second spell at Stamford Bridge, he shipped midfielder Juan Mata to Manchester United but then made him a key component when they met up again at Old Trafford.
He also re-signed Zlatan Ibrahimovic at United, who he had managed during his first season at Inter. In his second season, he brought Matic on board as well as Romelu Lukaku, who he had briefly been with at Chelsea.
There were no familiar faces during his short time at Tottenham Hotspur but at Roma he again found two of his former United stars in Chris Smalling and Henrikh Mkhitaryan.
Mkhitaryan, like Mata, struggled to find a regular starting spot under Mourinho and was sent to Arsenal in an exchange for Alexis Sanchez only to play a leading role at Roma.
