<a href="https://www.cricketcountry.com/teams/india/">India</a> great <a href="https://www.cricketcountry.com/players/sunil-gavaskar/">Sunil Gavaskar</a> says the pressure will be on <a href="https://www.cricketcountry.com/teams/pakistan/">Pakistan</a> in Sunday's highly anticipated <a href="https://www.cricketcountry.com/series/icc-cricket-world-cup-2019-200898/">World Cup</a> clash between the arch-rivals but believes the weather could play a key role. <p></p> <p></p><a href="https://www.cricketcountry.com/players/virat-kohli/news/">Virat Kohli</a>'s India start as favourites in the round-robin match at Old Trafford, with two wins and a no result so far. Pakistan, led by <a href="https://www.cricketcountry.com/tag/sarfaraz-ahmed">Sarfaraz Ahmed</a>, are struggling, with just one win -- an upset against hosts England -- two defeats and a washout. <p></p> <p></p>"It's a must-win game for them (Pakistan). If they don't win tomorrow, it'll be very tough," Gavaskar wrote in a column for the International Cricket Council. "The fact it's an old rivalry means it will be followed closely by the people of both countries, but Pakistan have had a bit of a stumble so far so there's probably a bit more pressure on them." <p></p> <p></p>Games between the two countries, who currently only face each other in multi-nation tournaments, are always about more than just what happens on the pitch. But the threat of rain looms large over the high-profile contest, which is expected to be watched by up to one billion people on TV. <p></p> <p></p>"If it's a proper 50-overs game I think India have the strength to win," said Gavaskar, who was part of India's World Cup-winning squad in 1983. But if gets truncated, if it's a game that gets reduced to 30 overs or less, anything can happen." <p></p> <p></p>Gavaskar though firmly believes that England remain favourites to win the 50-over showpiece event following their eight-wicket win over the West Indies on Friday. <p></p> <p></p>"My favourites for the last three years have always been England," said the cricketer-turned-commentator. <p></p> <p></p>"Their opening batting and their bowling attack have been fantastic, but I think more than anything else it's the leadership they've got." <p></p> <p></p>"The way England have been playing and the way they have recovered after losing to Pakistan doesn't bode too well for the other teams," he said. <p></p> <p></p>The Eoin Morgan-led side have won three of their four league games and are third in the 10-team table led by defending champions Australia, who have played five matches.
