'Worst player in the Premier League' is a debate for another day I feel. Will keep an eye on Gethin Jones though...

• West Ham will be hosting Shrewsbury for the first time since September 1980, when the Hammers ran out 3-0 winners in a second-tier clash.
• West Ham have won each of their past seven FA Cup home matches against lower-league opponents, scoring 20 goals (avg 2.9 goals per game).
• However, the Hammers have lost each of their past four FA Cup replays against sides from the Championship or lower, failing to score in the past three.
• The Shrews have never won an FA Cup encounter away to a top-flight side, losing nine and drawing one - with their last such match coming in February 1984, a 3-0 loss to Everton.

I thought Kelechi Iheanacho was going to be a cracking signing for Leicester last summer but he has not hit the ground running. At all.

He's scored once, in the League Cup.

It looks a pretty much standard formation. I think if you look at Leicester’s set-up, it’s a 4-3-3 going forward and a 4-5-1 when defending. I think it’ll be a bit more attacking than normal.

The players will have to get used to a subdued atmosphere. But this is a real opportunity for Kelechi Iheanacho to get his City career going in the right direction

Leicester City and England striker Jamie Vardy relives his 2011-12 season at Fleetwood Town, where his 31 league goals helped them win promotion to the Football League.

Spanish striker Toni Martinez makes his first start for West Ham as part of seven changes following Saturday's win over Huddersfield.

Martinez made his first West Ham appearance in the first game between the sides as a second half substitute for Chicharito. He already has FA Cup pedigree having scored twice while on loan at Oxford United last season, including in their win over Newcastle United in the fourth round.

Goalkeeper Joe Hart returns again to face his former club.

For Shrewsbury, the visitors have made three changes from Saturday's league defeat by promotion rivals Blackburn Rovers, with Joe Riley, Max Lowe and Stefan Payne coming into the side.

The Video Assistant Review (VAR) system faces an amendment after it made its debut in English competition.

VAR was used in the FA Cup tie between Brighton and Crystal Palace and again in the Carabao Cup match between Chelsea and Arsenal.

Referees boss Mike Riley said there could be a change to the official's 'finger to ear' signal for VAR.

He told BBC Radio 5 live: "We're coming up with ideas to make that more effective."

The video assistant referee (VAR) will be used in the FA Cup third round replays between Chelsea and Norwich, and Leicester City and Fleetwood Town.

VAR was used for the first time in a competitive English club game as Brighton beat Crystal Palace 2-1 in the FA Cup third round last week.

Our fifth 0-0 to recap. My word. The day the football died.

I would say Shrewsbury's best chance has gone. They had a real opportunity to win at home but they still have an opportunity, they are a good side.

West Ham have put out a fairly strong side, David Moyes has got them organised and worked hard on fitness.

ANOTHER 0-0. Joe Hart played though, and wore a cap handed to him by the away end.

It's forecast to snow hard tonight in some parts of England so I wouldn't recommend taking your grandma out - but Steve Evans says different!

"Come on – if your granny's not been out for a while, bring her here," the Mansfield boss says.

"I'm sure she's got Mansfield right through the middle of her, or [bring] your grandad.

"Let's have a sell-out in the home end. Let's make sure there's not a spare seat in the home end.

"Let the kids have a late day to school. Not because we need the last 200 tickets sold, but because we need the stadium rocking and rolling."

The winners of Mansfield v Cardiff will host Manchester City in the pick of the draws for tonight's sides, and it means a rare sell-out at Field Mill.

Keep hold of your stubs!

See the full fourth-round draw here.

It was another 0-0 up at Carlisle - Atdhe Nuhiu headed against the bar for the visitors in the first minute and also saw a close-range shot saved.

Sam Cosgrove had a Carlisle goal ruled out for offside before Jack Bonham brilliantly kept out a Nuhiu header.
