David Marshall would have ensured promotion last season

Marshall missed the final four months of last season with an elbow injury, that eventually required surgery.

I believe, with the benefit of hindsight and taking in to consideration what took place in his absence, that Cardiff would be in the midst of a Premier League campaign had they been able to utilise a fully fit Marshall.

Marshall has had his fair share of ups and downs in his two and a bit years at the club, the highlight being his performance in the second leg of the 2010 play off semi final with Leicester.

One of his worst performances was in the subsequent play off final against Blackpool, although it would appear that his performance was hindered by his elbow injury.

"I injured my elbow in the play off semi-final against Leicester City," revealed Marshall."
"I tried to play on at the start of last season but the elbow problem just got worse. I realised in February I needed an operation."

Marshall was not at his best last term, in and out of the side with Heaton deputising, before injury finally ended his campaign.

Unfortunately Heaton sustained a groin injury that resulted in the arrival of Stephen Bywater on loan and the beginning of the end, with regards to Cardiff's promotion aspirations.

The dismissal of Dave Jones and the arrival of Malky Mackay ensured that the battle for the number one shirt would be based on training and pre-season displays. Mackay appeared to be undecided right up until the opening fixture at West Ham, he eventually opted for Marshall and his choice was vindicated by a man of the match performance.

The Scot has impressed this season behind a new look back four, earning plaudits from Mackay in the process.

"He had a good pre-season and has forced his way back into the Scotland squad.

"It's testament to the hard work he's putting in.

"Goalkeepers are all about confidence and I'm looking at someone who is ice-cool at the back.

"I'm really happy with him" explained Mackay.

Long-standing issues relating to dominating his box and dealing with crosses remain, but his overall performances have been of a consistently high standard.

Marshall was withdrawn at half time in the recent 3-0 win at Derby due to illness, with Heaton taking over and playing his part in ensuring that a clean sheet accompanied a resounding win.

He also lined up in the 2-0 win over Crystal Palace, Marshall's absence was not keenly felt during this period, although Heaton was practically unemployed during these fixtures.

Marshall is available for Saturday's trip to Reading and is likely to be restored to the starting line-up, which would be harsh on Heaton, who has done nothing wrong in his first two league outings.

Marshall has surely done enough to ensure a swift return to the side and his return is a welcome boost, had he been able to return to the Cardiff side last season, things may he have turned out very differently.
