Well, I may be in the minority but when he is fit I like the way he plays. He offers a bit of aggression (which we sorely lack), pace and willingness to make something happen. If the rumours are true and FF is off to warm the bench at Cardiff then Matias may well be the only way we can inject some invention into the side. when he played the few games in January and February, I think in partnership with Joao up front, he looked quite dangerous. Think they were mainly cup games though so against lower league opposition.
Personally, I'd like to see him get a run out with Joao and maybe Fletcher in a 3 up front on Saturday.
