That's the sort of thing that happens with good coaching linked with proper fitness programs and the correct diet. Joelintion is far from a yard dog. He initially played as a striker and was rubbish. He has been moved to be a midfielder and he is excelling. It is coaching that has turned him from your one season assessment of a yard dog into a top quality midfieldThey're doping imo.
Whiff of Liverpool over the past few years with yard dogs like Joelinton and Longstaff running around 100mph never tiring and scoring within the opening 5-10 minutes every game.
