Pep Guardiola expects Rodri to be "out for a long time", though Manchester City are still waiting for official confirmation on the extent of the midfielder's injury.

Rodri sustained a serious-looking knee injury during a corner in City's 2-2 draw with Arsenal on Sunday, having turned awkwardly while tiusslinThomas Partey.

The former Atletico Madrid man has since been seen in Barcelona, with reports suggesting that he has suffered an anterior cruciate ligament (ACL) injury.

That would possibly keep him out for the season and would be a huge blow to City, for whom he has proven to be a key man since joining in 2019.

Before City's EFL Cup third-round tie with Watford, which they won 2-1 to progress to the next round, Guardiola was unable to offer any updates on his condition.

However, in his post-match interview, Guardiola conceded that he would be without the Spain international for a prolonged period.

"Rodri will be out for a long time, a while," Guardiola said.

"There are some opinions that it will be less than we thought, but we are waiting for the last phone calls from him and the doctors for what definitely he has and the type of surgery he has to get. We should know tomorrow."

Rodri played 50 times for City in all competitions last season, losing just one of those matches.

However, in the nine they played without him, their win percentage dropped from 76% to 55.6%, with their points-per-game dropping from 2.5 to 1.7.

And Guardiola knows the onus will be on him to find a solution.

"When a team doesn't play with the best midfielder in the world for a long, long time, it is a big blow," Guardiola told reporters.

"Yes, he's irreplaceable. But my duty is to find a solution.

"There is an alternative, we will do it. When you have one player who is irreplaceable, as a team we have to find a solution."

The Premier League witnessed drama at both ends of the table on an absorbing Saturday, as Manchester City and Liverpool continued to trade blows in the title race.

Jurgen Klopp's men downed in-form Newcastle United thanks to Naby Keita's first-half strike, before City responded by cruising to a 4-0 thrashing of Leeds United at Elland Road.

At the other end of the table, Norwich City were condemned to a record sixth Premier League relegation at Aston Villa, and Watford look destined to join them after Burnley continued their incredible upturn in form at Vicarage Road.

After another frantic day of action, Stats Perform looks at some of the key Opta facts from Saturday's contests.

Newcastle United 0-1 Liverpool: Keita continues Reds' run

Liverpool's bid for a remarkable quadruple faced a tough test when they travelled to Eddie Howe's in-form Newcastle in the first clash of the day.

However, Naby Keita's 19th-minute goal proved the difference in a competitive encounter, and was Liverpool's earliest winning goal in a 1-0 Premier League victory since December 2016, when Georginio Wijnaldum netted after eight minutes against Manchester City.

Klopp's side had chances to extend their lead, with home goalkeeper Martin Dubravka making nine saves, his highest tally in a single Premier League match. Since 2003-04, when Opta data began, the only Newcastle goalkeepers to make more saves in a Premier League game are Tim Krul (14 against Tottenham in November 2013) and Karl Darlow (11 against Tottenham in September 2020).

However, a 21st clean sheet of Liverpool's league campaign was enough to move them to the top of the table - only in 2005-06 (22) have the Reds kept more shutouts in a single Premier League campaign.

Liverpool have now picked up 40 points from the last 42 on offer in the competition, and the win turned up the pressure on City ahead of their trip to Leeds later on Saturday.

Leeds United 0-4 Manchester City: Visitors draw on set-peice prowess to reclaim top spot

The Reds were not top of the table for long, however, as City claimed a 4-0 win over relegation-threatened Leeds at Elland Road. Goals from Rodri and Nathan Ake both came from set pieces, meaning City have now scored 18 set-piece goals (excluding penalties) this season, their most in a Premier League campaign since 2013-14 (22).

Pep Guardiola's men have also kept five consecutive away league clean sheets, the best such sequence in the club's history.

After Gabriel Jesus had made the points safe, Fernandinho stuck a superb fourth goal late on, becoming the club's oldest ever Premier League goalscorer at 36 years and 361 days old, overtaking Frank Lampard in 2015 (36 years and 338 days old).

Leeds, meanwhile, are looking over their shoulders after another heavy defeat. They have conceded a remarkable 20 league goals against the two Manchester clubs this season (11 against City, nine against Manchester United) – a new top-flight record for goals conceded against the duo in a single season.

Watford 1-2 Burnley: Clarets' revival continues after Cork ends barren run

Elsewhere, Burnley continued their incredible revival by coming from behind to defeat Watford, making Mike Jackson the first Clarets boss to win three of his first four league games in charge since Jimmy Mullen won his first four in 1991.

After James Tarkowski's own-goal put Watford ahead, Jack Cork ended his run of 84 Premier League games without a goal with his first strike since December 2018 (against Liverpool), before Josh Brownhill scored a late winner.

The Clarets are now five points above the bottom three after winning three consecutive Premier League games for the first time since April 2019, having won just three of their previous 21 games.

Roy Hodgson's Watford, meanwhile, look destined for relegation after becoming the first side in English top-flight history to lose 11 consecutive home league matches.

Aston Villa 2-0 Norwich City: Canaries suffer another relegation at Villa Park

Burnley's win had other ramifications, contributing to Norwich suffering their sixth relegation from the Premier League – the most of any club in the competition's history – after the Canaries were beaten at Villa Park.

Remarkably, Norwich have been relegated in each of their last four Premier League seasons (2013-14, 2015-16, 2019-20 and 2021-22). They are only the second side in English league history to suffer relegation in four consecutive campaigns in the top-flight, after Crystal Palace (1992-93, 1994-95, 1997-98 and 2004-05).

Dean Smith's men saw their fate sealed after becoming the first team to concede 70 Premier League goals this season after just 34 games, representing the earliest point in any league campaign they have reached 70 concessions since 1956-57 (in their 34th game in the old Third Division South).

Ollie Watkins set the tone for Villa's win with his first-half strike, and he has now scored at least 11 more goals than any other Villa player since his September 2020 debut (25 goals in all competitions).

Should Jack Grealish be starting? Should Harry Kane be in the penalty area more often? Does Jadon Sancho still exist?

All these questions and more are whipping around the usual major tournament maelstrom for England, as Gareth Southgate's under-pressure side prepare for their final Group D game against the Czech Republic.

A dour 0-0 draw against Scotland means the feelgood factor that followed the Three Lions' opening 1-0 win over Croatia has largely dissipated, with ample debate surrounding multiple positions in the line-up – particularly the understudies to a talent-stacked forward line after three shots on target over the course of 180 minutes.

Further back, things feel more settled and Southgate would surely be loath to make unnecessary changes in midfield if self-isolation rules out Chelsea playmaker Mason Mount.

Declan Rice has become a mainstay for the England boss and feels like a virtually certain starter against the Czechs, but is the West Ham favourite making enough of a positive impact to merit that status?

Dropping anchor in the England midfield

Since Rice was persuaded to switch allegiance from the Republic of Ireland, who he represented in three international friendlies in 2018, Southgate has made the 22-year-old a key pillar of his side.

Of his 19 England appearances, 17 have been starts. Since making his debut from the bench in the opening Euro 2020 qualifier – when the Czech Republic were dispatched 5-0 at Wembley – two of the four competitive games in which Rice has not featured were the third-place match against Switzerland in the Nations League Finals and the formality of a World Cup qualifier versus San Marino.

The other two, perhaps tellingly in the eyes of some critics, were back-to-back European Championship qualifiers against Bulgaria and Montenegro that England won 6-0 and 7-0 in an expansive 4-3-3 setup.

There is a sense that a midfield axis of Rice and Kalvin Phillips represents undue caution on Southgate's behalf, leaving the team arguably light in the attacking-midfield positions where there is such a depth of options.

Phillips laid on Raheem Sterling's winner against Croatia and won deserved plaudits for an all-action display but the influence of Rice, whose performances at club level have impressed to the extent he has reportedly caught the attention of Chelsea and Manchester United, has been harder to spot.

Creator? Destroyer? Neither?

Of course, it is the lot of the defensive midfielder that plenty of their best work goes unnoticed, in both attack and defence. So, has Rice been quietly compiling impressive displays under the radar?

The numbers from England's first two Euro 2020 matches would suggest not. Across both of those games, he has made one tackle, no interceptions and recovered possession seven times.

Examining some players performing similar roles for teams with comparable pre-tournament hopes of success to England, Spain's Rodri and the Netherlands' Marten de Roon also made a tackle apiece across the first two match days. However, De Roon boasted three interceptions and 12 recoveries – the latter the same as Phillips, incidentally – and Rodri has two and 11 on those metrics.

Jorginho, whose club status at Chelsea would come into question were those Rice rumours to come to fruition, has been the conductor for Italy. After starting all three group victories for Roberto Mancini's side, the former Napoli player – not noted as an overly combative presence – made three tackles, seven interceptions and 16 recoveries.

Within a free-flowing Azzurri, Jorginho has also created five chances, which feels like an over-performance for a player in his role considering the numbers for De Roon (two), Rodri (one) and Rice (zero).

Nevertheless, even if holding players do not always contribute directly to goal attempts, their creative influence can be vital at the fulcrum of the side.

Rice and De Roon have each been involved in five open-play sequences leading to shots, with Rodri on seven and Jorginho way out in front on 18.

The Italy man's average carry progress - the distance he moves vertically upfield when in possession of the ball - is 5.6 metres, ahead of De Roon's 3.2m.

There is little argument Italy and the Netherlands have provided far more entertainment value than Spain and England, with Rodri and Rice's progressive carry averages clocking a far more conservative 1.9m and 1.6m respectively.

This is despite Rice's average carry distance overall being 10.8m, more than his three counterparts, meaning he is moving a lot with the ball at his feet but not often forwards.

Shackled by Southgate?

Those figures create an unhelpful picture of a player not being particularly prolific in terms of snuffing out opposition attacks or launching them for his own team.

If Rice had been making comparable contributions at West Ham it is unlikely he would be anywhere near the England side and the drop-off from his club productivity for the opening two games of the Euros is stark.

During an impressive 2020-21 for David Moyes' side, Rice's averaged 6.1m for progressive carries and 12m overall.

His club v country disparity is comparable to Rodri, who clocked a 5m average for progressive carries for Premier League winners Manchester City. In this sense, Mancini's achievement with Jorginho is providing a structure where he can reach similar levels of effectiveness to those he does at Chelsea (4.7m per progressive carry).

Rice's carries led to four shots for the player himself during West Ham games last term (one goal) and five assists. Rodri fired five shots and created as many chances in this manner, with Jorginho and Atalanta's De Roon creating three and one chances respectively without attempting a shot between them.

For the Hammers, Rice averaged 7.28 recoveries per game and 1.84 for both tackles and interceptions, once again suggesting far more active and impactful displays than he has produced – or been allowed to produce - for England.

Much of the discussion around the England team has concerned whether Southgate should loosen the shackles on his full-backs and in central areas to give his attacking players a more progressive platform. Perhaps, in the case of his first-choice holding midfielder, part of the answer is already in the XI.

If Rice can bring his West Ham levels of influence to bear on the international stage, it could help England to be a more assertive presence overall. If his low-output efforts remain, then the likes of Jordan Henderson and Jude Bellingham should be asked to supply the midfield thrust he has failed to provide so far at Euro 2020.
