Grant McCann will have found it easier had he left his office door wide open the past few days to help with the procession of players coming through it.

An opportunity to play at the London Stadium against a Premier League side in West Ham has that ability to ensure no member of the squad wants to miss out and those who featured against Crewe Alexandra on Saturday will have wanted to offer their own little reminder that they didn’t want to sit out this Carabao Cup third round match.

It will be with great anticipation the confirmed teams will be examined tonight, with interest on both sides of who is, or in some cases, isn’t playing.

As much as any position on the pitch this evening, McCann’s team selection at goalkeeper could well be the most scrutinised.

In five matches so far this season last season’s first choice goalkeeper George Long is yet to get a look in. Amid speculation of a falling out or a desire to move the keeper on, City boss McCann has insisted all is well between the player and club with his early absence due to an injury picked up at training.

That may be so, but it’s clear there is a new number one emerging at City. Matt Ingram has started the two League One and Carabao Cup matches so far, only rested for the EFL Trophy match with Leicester City’s Under23s, a game that saw Harvey Cartwright and not Long selected in Ingram’s place.

The Hull players warm up before the Championship match at the Cardiff City Stadium

There is of course a tendency to read too much into Cartwright’s selection when McCann had picked a young side to take on the Foxes and will have wanted to see his number three in the senior environment, with Long likely to have not trained enough after injury.

As so often with these cases, there’s a caveat. Ingram may have got the nod for the opening games because of Long’s injury, but he’s held onto the shirt in commanding style and keeping three clean sheets in four appearances is pushing Long further out of contention. There’s no denying Long’s position at the club has changed.

The current holder of the number one jersey has not played since letting in three goals against Cardiff City last season, that display coming eight days after picking the ball out of his net eight times against Wigan Athletic.

In contrast, Ingram’s only goal conceded in four games is the late equaliser at Elland Road against Leeds United in the cup.

“Matt should have four clean sheets. He’s got three,” explains McCann.

“He’s been really calm and you can hear his voice behind the back four. He has had to wait patiently for his chance.

"I am lucky that I have four very good goalkeepers. We have two excellent young goalkeepers who represent England and Wales, underneath the senior two. Matt has been excellent.”

There’s no denying a changing of the guard has taken place, but for how long? Managers so often use the cup games as an opportunity to give their second choice keeper much-needed game tie, so will Long come in at the London Stadium tonight?

“We’ll see,” McCann told the BBC. “George will definitely come into the thinking of course.”

While who starts in goal will be analysed for its importance, fans will be looking to see if one name appears on the opposition team sheet.

Eight months after leaving City, the Tigers could face off against Jarrod Bowen for the first time. Named on the bench for the Hammers’ win last time out against Charlton Athletic, there will be great interest in whether the young man who lit up the KCOM by tearing teams apart will be employed to do just that against his former side.

“They have a massive squad and made 11 changes in the last game against Charlton. They have top players there and it will be nice to see Jarrod again,” added McCann.

“I haven’t seen him personally since he left the football club in January and it will be good to see him again.

"We hope he has a quiet evening if he plays.”
