sport news David Seaman on brilliant Martinez, error-strewn Kepa and THAT FA Cup save ...

The goalkeeper who won four FA Cups with Arsenal is discussing the difference between Kepa Arrizabalaga and Emiliano Martinez, namely how one broke the golden rule while the other didn’t.

‘If you don’t stop the ball when you should do,’ explains David Seaman, the Arsenal and England icon speaking to Sportsmail ahead of his former club’s final against Chelsea today.

‘That’s what you live and die by. If you start making mistakes, then you’re going to get left out.’

Simple then. Kepa made too many of those for Frank Lampard’s liking while with Martinez it’s the opposite. Indeed in this Argentinian, Arsenal might have found a new No 1.

Bernd Leno is training again but he’s watched on helplessly as his understudy stakes his claim. It’s certainly left an impression on Seaman, who says: 'He has taken his chance.

‘He’s got every quality you need. Great physique, big goalkeeper, great with his feet.

‘I hate that word “shot-stopper” – that’s what you are if you’re a goalie. But his goalkeeping skills are brilliant. His distribution, his saves, his crosses. I love his confidence at taking crosses.

‘It will be a really difficult decision for Mikel Arteta when it comes to next season.’

It will be painful for Kepa to watch from the sidelines at Wembley Stadium today.

On how a lack of confidence can seemingly kill a goalkeeper, Seaman tells Sportsmail: 'I remember when Scott Carson played for England on his competitive debut against Croatia.

‘He made a really bad mistake inside the first five minutes and his confidence went. Some goalkeepers react like that, some get on with it. But the manager spots that in goalkeepers.’

Arsenal insiders say Arsene Wenger had designs on making Martinez the club’s first-choice goalkeeper before the 70-year-old Frenchman departed after more than two decades in charge.
