Holloway said: â€œAruna has been training with us and we have seen what was needed to get him up to our level of fitness, so very quietly behind the scenes we have been working with him to get him to the condition that we want. I am hoping he returns to what I have seen him play like before.
â€œHe has been working hard to reach those levels and if he can do that he might add something to the group that could help us in the weeks to come. Heâ€™s very strong and a goalscorer and I know what he can bring to us if he is in the right condition.
â€œI would like to thank the chairman for giving me the chance to bring him in and we will see what he can do for us.â€
Vi ønsker Aruna velkommen til klubben
