“Slowly but surely he’s starting to show people what he can do, and hopefully there will be a lot more to come.
“The Owen-Martins combination certainly has potential without a doubt, but don’t forget Shola: he’s had a serious injury too.
“He’ll come back into the fold, and when they have got everyone fit they will be a match for more than most.
“They’re all going to get goals, will complement each other well and hopefully can strike up a really good understanding together.
“Plenty of sides will be jealous of that trio, that’s for sure.”
