Birmingham City close in on Ogenyi Onazi

According to SkySports, Birmingham City Football Club have agreed to a deal for Trabzonspor's Ogenyi Onazi. The Nigeria international joined Trabzonspor last summer from SSS Lazio and made 33 Super Lig appearances during his debut season in Turkey.

Ogenyi Onazi still has three years remaining on his current contract with Trabzonspor, but now it seems that he'll be heading to Birmingham City in the coming days should a deal for Torino's Afriyie Acquah fail to finalize. Last Wednesday, the Blues put up a $9.3 million bid to sign fellow central midfielder Afriyie Acquah from Torino.

Marten de Roon set to return to former club

Middlesbrough has accepted a fee to allow Marten de Roon to join Serie A club Atalanta, according to BBC Sport. The Teessiders spent heavily during the summer transfer window with $19 million forward Britt Assombalonga heading a list of new signings which also includes Jonny Howson, Cyrus Christie, Martin Braithwaite, Ashley Fletcher, and Darren Randolph. Marten de Roon, 26, joined Middlesbrough Football Club from Atalanta last year summer for a price of roughly $15 million, and now he is set to make a return to Italy this summer.

Marseille gives up chase to sign Olivier Giroud

According to 90min, Marseille head coach Rudi Garcia has lost all hope of landing Arsenal's Olivier Giroud this summer. Olympique Marseille boss Rudi Garcia told reporters: “I don't think Giroud want to come to Marseille, that's just the problem. It is understandable as he is a striker with the France national team and also making progress with Arsenal. I think his interest might lie beyond Olympique Marseille." Olivier Giroud has been linked with a move away from Arsenal after struggling to earn a regular spot in the Gunners' starting XI line up the last term. Early this summer, compatriot Alexandre Lacazette arrived at Arsenal in a “big money” move from Olympique Lyon, a move which will likely damage Olivier Giroud's hopes of securing more playing time this season.
