Nigel Martyn believes Leeds United would be telling Kiko Casilla that he is not good enough if they pursue a deal for Manchester United goalkeeper Dean Henderson in January.
Henderson, 23, impressed during his two seasons on loan at Sheffield United, helping them win promotion to the Premier League and then secure a ninth-place finish in the top-flight.
However, the one-time England international has since returned to Old Trafford and barely played for Ole Gunnar Solskjaer’s side with just three appearances in all competitions.
According to a report by The Sun at the weekend, Henderson is keen to leave Man United on loan again so that he improves his chances of earning a call-up for England at the European Championships next summer.
It is understood that Leeds and Premier League rivals Brighton could look into signing the Cumbria-born shot-stopper on loan in January but, ultimately, Man United and Solskjaer will have the final say.
Ex-Leeds goalkeeper Martyn maintains that while Henderson would be a solid addition to Marcelo Bielsa’s options in between the sticks, he has warned the Whites about upsetting the current shot-stoppers at the club.
“He would be a good signing, given how well he played for Sheffield United,” Martyn told The Boot Room. “It would be harsh on [Illan] Meslier, but he’s only 20. He’s one for the future. I’d like a more senior goalkeeper, but there is no reason to change it.
“If they go after Henderson, it’s worrying for [Kiko] Casilla. It means he is not turning to him, and if you’re trying to get Henderson on loan – it needs to be with a view to buying it. If Man United don’t want to sell, you’re upsetting your goalkeeping department.
“If they were in to buy him, and Man United were to let him go – I would be happier that route. To get him on loan it doesn’t send the best vibes to Meslier, it says to Kiko that you aren’t good enough.”
Meslier, 20, has impressed for Leeds so far this season even though the Whites have the second-worst defensive record in the division.
According to stats by WyScout, the French youngster ranks fifth in the Premier League for the number of saves made  but he ranks down in 10th for the number of prevented goals [0.52].
It means Meslier isn’t doing any out of the ordinary when it comes to making his saves but he’s still been able to prevent what should have been a goal hot every other game.
As for Casilla, where do we start?
The Spanish veteran was suspended for racial abuse last season and his performances have been nowhere near that of which has been required at Elland Road.
We would like to see him leave as soon as possible but there’s no way the Whites would sign Henderson, a reported £100,000-a-week player, to stick him on the bench.
If he comes in, he would more than likely be replacing Meslier and as Martyn says, that would be a bit demoralising for a youngster who hasn’t done much wrong.
