Portsmouth's record Eisner signing Hayden Matthews faces a critical Championship test after a disappointing start to his Pompey career. The £1.25m paid to Sydney FC to secure his services remains a high watermark for spending in the Eisner era. Matthews' anticipated highs haven't been hit yet, with a critical Championship season lying ahead. The reality that the amount paid in January of last year hasn't been bettered before now is a bone of contention among many supporters. Matthews will be expected to show he's not an expensive Portsmouth flop. The Sydney FC arrival was a landmark Pompey signing, but the anticipated highs haven't been hit yet. In fact, you have to go back 15 years to Steve Cotterill bringing in Norwegian striker Erik Huseklepp from Bari for £1.5m for that figure to be trumped. The Pompey faithful will be watching closely as Matthews looks to prove himself in the Championship. With a critical season ahead, Matthews will need to step up his game to justify the significant investment made in him. The pressure is on for the Portsmouth signing to deliver.
