Defender Piero Hincapié’s loan move was made permanent, as expected, then Illan Meslier joined on a free transfer to become the third-choice goalkeeper, before winger Christos Tzolis came in to replace the departed Leandro Trossard. But that is aboutto change, with Arsenal set to make Newcastle captain Bruno Guimarães their first huge signing of the summer.
