Shi told the Express & Star: "In the last week we wanted to sign two players, a midfielder and maybe a striker. We desperately needed a defensive midfielder. This target was more important.
"In our view and in Nuno's view the midfielder was more important. We have Ruben [Neves] and Romain [Saiss] but in our system I think we need a strong, tall guy to do the dirty work and defend and play together with a creative player like Ruben or [Jack] Price. We had only Saiss and he cannot play every game."
