Victor said: "Southampton is a good club and it has good players, so I just want to train hard and work hard to be a part of the starting XI. We'll see where that will take me. It feels great and I am happy to be here. There were other options, but Southampton is a club with ambitions so I chose to come here. I'm very grateful to be here and I'm looking forward to playing in the Premier League."
