DUNDEE UNITED boss Gordon Chisholm last night ordered misfiring striker Collin Samuel to get his act together.
The Trinidad and Tobago star,left,has been at Tannadice for two years and Chisholm said: 'He has skill and speed no one else in the side has.
'But he lets himself down with silly little things by choosing the wrong option.He has to concentrate because he can't keep living on potential.'
