Grzegorz Krychowiak and Kamil Piatkowski are the latest Poland players to test positive for coronavirus ahead of the World Cup qualifier against England on Wednesday.

Midfielder Mateusz Klich was the first squad member to return a positive COVID-19 test last week and it was revealed on Saturday that goalkeeper Łukasz Skorupski had also contracted the virus.

Polish Football Association spokesman Jakub Kwiatkowski confirmed midfielder Krychowiak and defender Piatkowski have now tested positive on the eve of the clash with Group I leaders England at Wembley.

Kwiatkowski tweeted: "The Polish national team has undergone further tests for the presence of coronavirus.

"Unfortunately, the results of Grzegorz Krychowiak and Kamil Piatkowski are positive. Due to the fact that Krychowiak is a recovering man, we started talks with UEFA in order to clarify the matter and admit him to the match."

Kwiatkowski said he too had tested positive for COVID-19.

Prolific Poland captain Robert Lewandowski has also been ruled out of the encounter with Gareth Southgate's side due to a knee injury.

Robert Lewandowski has returned to Bayern Munich to receive treatment on a knee injury, Poland have confirmed.

The striker sustained damage to the collateral ligament of his right knee during the 3-0 World Cup qualifying win over Andorra, in which he scored twice.

Poland issued a statement on Monday to confirm Lewandowski will miss their match with England on Wednesday in order to avoid the risk of aggravating the injury.

The 32-year-old will instead return to Germany for further treatment, which is expected to last from five to 10 days.

The news will be of concern to Bayern coach Hansi Flick ahead of a tough run of fixtures for the Bundesliga leaders.

Bayern face RB Leipzig on April 3, four days before the first leg of their Champions League quarter-final against Paris Saint-Germain.

The German champions then host Union Berlin on April 10 ahead of the return leg away to PSG on April 13.

Lewandowski has scored 42 goals and provided eight assists in 36 appearances in all competitions for Bayern this season.

The former Borussia Dortmund star has at least 10 more direct goal involvements in 2020-21 than any other Bundesliga player.

Harry Kane set his sights on Poland after scoring one goal and creating another for Mason Mount in England's 2-0 World Cup qualifying victory over Albania.

Kane had gone six games without finding the back of the net for his country before opening the scoring with a first-half header at the Air Albania Stadium in Tirana on Sunday.

The Three Lions captain turned provider after the break, picking out Mount with a measured pass which the Chelsea midfielder controlled in an instant before dinking over goalkeeper Etrit Berisha and into the back of the net.

Kane and Phil Foden also struck the woodwork in a dominant display from Gareth Southgate's side, who have started their bid to qualify for next year's tournament in Qatar with straightforward victories over San Marino and now Albania.

A much bigger test is expected when England face Poland in Group I on Wednesday, but captain Kane says they will go into that showdown with great confidence.

The Tottenham striker told ITV Sport: "I thought it was a really good performance, maybe a bit slow at the start but we changed our formation and I think that helped.

"Sometimes you go through spells when things don't go your way, that is part of being a striker. You just have to stay focused and it was great to get three points.

"We need to keep working hard but we are in a good place. Poland will be the toughest game in the group but we are ready for that. If we can win that, that puts us in a great position."

England talisman Kane has now had a direct hand in 18 goals in his last 13 games at international level, scoring 11 and providing seven assists.

The 27-year-old's header ensured he has scored in each of his last seven away qualifying matches, the longest ever run by an England player.

The international break might bring respite from the packed club calendar, but with Qatar 2022 now just 20 months away, top players have little chance for rest.

Still, the start of the European World Cup qualifiers brings an opportunity for the new names on the international scene to impress, particularly with more established stars unlikely to be involved in every minute of matches over these two weeks.

Several of the continent's top teams have offered first-time call-ups to those enjoying fine form and, while some were anticipated, others have left even the players themselves surprised.

We have picked through a selection of the new faces to look out for, with a sprinkling of Opta data to highlight why they deserve a chance to impress for their country.

Belgium: Orel Mangala and Albert Sambi Lokonga

Stuttgart's Orel Mangala has been linked with Arsenal and RB Leipzig due to his performances for Stuttgart this season. Only three midfielders have regained possession more often in the Bundesliga than the 23-year-old (166).

Also hoping to make his senior Belgium debut at the heart of midfield is Albert Sambi Lokonga, who assumed the captain's armband at Anderlecht less than a month after turning 21.

Lokonga, who could get a chance in place of the injured Axel Witsel, has regained possession 35 more times than any team-mate this season (157) and is also fourth for chances created (22).

Croatia: Kristijan Lovric

With Ante Rebic and Bruno Petkovic injured, the coming matches could offer a real chance to impress for Kristijan Lovric.

The HNK Gorica star is second in the top scorer standings in Croatia's top flight, with 15 goals in 24 appearances. With four assists also to his name, Lovric is behind only Tottenham's Europa League slayer Mislav Orsic and Ramon Mierez (both on 20) for direct goal involvements this season.

It's a seriously impressive return for the 25-year-old, particularly as he plays predominantly wide on the left of the Gorica attack.

England: Ollie Watkins

West Brom goalkeeper Sam Johnstone may get the chance to win a first senior England cap, but a man almost certain to be given a chance in attack is Ollie Watkins.

The Aston Villa forward became the 10th Premier League player to score a hat-trick against Liverpool, and the first in a decade, in October's extraordinary 7-2 win over the reigning champions.

He has 10 in the top flight this term, while only captain Jack Grealish (17) has had more direct goal involvements than Watkins (15) in all competitions for Villa this season. Not bad for a man who was playing in England's sixth tier just six years ago.

Germany: Florian Wirtz and Jamal Musiala

Rising Bayern Munich star Jamal Musiala was expected to be named in Joachim Low's squad after he pledged his international future to Germany rather than England.

The 18-year-old, who only signed his first professional contract this month, is Bayern's youngest ever Champions League goalscorer and has already played 18 times in the Bundesliga this season.

Bayer Leverkusen's Florian Wirtz has also earned the right to shine on the senior stage. He is one of just two players under the age of 20 to be directly involved in at least eight goals across the top-five European leagues this season.

Italy: Rafael Toloi and Matteo Ricci

Brazilian-born Rafael Toloi has made it to the age of 30 without a senior international appearance, but his performances for Gian Piero Gasperini's outstanding Atalanta side made him hard to overlook.

Toloi averages seven possession regains per match for Atalanta this season and is comfortable when using the ball, completing 493 passes in the opposition half, the most of any Atalanta defender barring Berat Djimsiti.

Spezia midfielder Matteo Ricci, meanwhile, boasts 19 chances created in Serie A this season as well as 151 times winning back the ball, by far the highest tally for his team.

Netherlands: Jeremiah St Juste

Jeremiah St Juste has impressed at the back for Mainz this season, despite their involvement in a tense battle to avoid the drop.

There are only five Bundesliga defenders to win more tackles and duels combined than the 24-year-old this season (he has managed 165).

Previously a full-back with Feyenoord, St Juste brings a vital commodity to modern central defending: speed. Last season, he clocked a sprint of 22.1 miles per hour, bettered only at the time by Bayern winger Kingsley Coman.

Poland: Kacper Kozlowski

A relative unknown outside Poland, even Kacper Kozlowski himself was shocked to be called up to Paulo Sousa's squad this month.

Clearly, though, he has caught the eye for some all-action displays in the top flight for Pogon Szczecin. The 17-year-old averages 8.3 duels won and 17 passes ending in the final third per 90 minutes, each the most of any teenage midfielder in the competition.

Kozlowski, who is also renowned for a fierce long-range shot, has been linked with some of the world's biggest clubs since making his senior debut at just 15, with Manchester United said to be among them.

Portugal: Joao Palhinha and Nuno Mendes

Linked with Manchester City (among others), Sporting CP full-back Nuno Mendes has been described as the standout young talent in Portugal's top flight.

Only Wilson Manafa (49) has completed more dribbles among defenders this season than Mendes (29), who has played in all but four of the unbeaten leaders' league matches.

The 18-year-old is joined in the Portugal squad by team-mate Joao Palhinha, a robust midfielder who has won 208 duels in the Primeira Liga in 2020-21 – no player in his position has won more.

Spain: Bryan Gil and Pedri

Pedri has been a revelation for Barcelona in his first season at Camp Nou, establishing himself as a key part of Ronald Koeman's midfield despite only turning 18 last November.

He has played 42 times already in 2020-21, the most of anyone at the club, and became the youngest player to record 100 touches in a single LaLiga game for at least 15 years against Osasuna this month.

Bryan Gil, meanwhile, has been thriving on loan at Eibar from Sevilla and in January became the second player born this century to score twice in the same LaLiga match, following in the footsteps of Ansu Fati.
