Lewis Hamilton, Sebastian Vettel and potential F1 driver changes as 'swap' rumours emerge

Formula One season is in full swing, with the opening four race weekends of the season providing plenty of talking points and surprises - with plenty more on the cards.After a record-breaking amount of races last season, with 22 in 20 countries, F1 is set to do it all again by raising the bar to 23 - assuming a replacement is found for the cancelled Russian Grand Prix, which is expected.That means that drivers who have had a slow start to the season still have time to turn it around, while those who have excelled cannot put their feet up yet - but further drama has been thrown into the mix with rumours of movement on the driver market.Spanish journalist Albert Fabrega teased at the weekend that a 'swap' on the grid could well be materialising, while rumours in the driver market also indicated that Oscar Piastri, highly-rated after victories in Formula 3 and Formula 2, could get a seat of his own.

Given the number of spots on the grid is limited to 20, any new arrival would mean a departure but there's enough rumours to leave a number of people sweating on their positions - and Daily Star Sport has taken a look at five in particular who are in the headlines.Nicolas LatifiThe Canadian driver has regularly been scrutinised for his position on the grid, due to the vast wealth of his father and his ties to the Williams team, but it's his performances on the track which have found him under the spotlight already this season.Now in his third season with Williams in Formula One, the team will have come to expect some results from him and optimism would have risen last year with a seven-point haul for the team which came in back-to-back races in Hungary and Belgium.Williams have a proud record of utilising young drivers, as shown.
