There is nothing placing Toni at the scene of the murder, not even a fibre. Plus there is no way she could have transferred all his fibres onto Alesha. The jury will not need long to convict him IMO. Whether or not Toni & Rab had a bad relationship, Toni was jealous, or had a secret sexual relationship with the accused. His defense is not believable for one second IMO.
The jury will have seen his demeanour in court and I would suggest that he does not come across as someone who has been wrongly accused - he comes across as someone who has the pathology of blaming others. He even sought to blame the police for what they would do before they did it. He also knew a guy had done something to Alesha before anyone knew.
