Premier League 
Chelsea travels to the Tottenham Hotspur Stadium this weekend for a London Derby this is a must-win for The Blues. The sides met controversially at Stamford Bridge at the start of the season, where Tottenham bagged a draw and avoided a clear red card.
Son Heung-Min returned to scoring ways against West Ham, helping Spurs to a 2 - 0 win and pushing them back up to fourth in the Premier League. Tottenham have fluctuated in quality with manager Antonio Conte away from the touchline, the Italian being sidelined after an operation, grabbing wins but also suffering shock losses.
In their last five Premier League games Tottenham have three wins and two losses. Despite leading 2 - 0 at half time, Spurs slumped to a 4 - 2 loss against Manchester City, though they would then go on to beat City 1 - 0 even with Cristian Romero seeing red in the final minutes. Spurs have also won two London derbies in those five matches, beating Fulham 1 - 0 and most recently securing a 2 - 0 win over West Ham. However, before returning to winning ways, Spurs did fall to a 4 - 1 defeat by Leicester and lost 1 - 0 in the first leg of their Last 16 Champions League tie against AC Milan.
Chelsea continued their miserable form despite all of the talent acquisitions in January. Even with their big-money signings starting, The Blues have failed to pick up any semblance of form, heaping even more pressure on manager Graham Potter as fans have already begun to call for his head.
Chelsea have just one win in their last five Premier League games, that being a 1 - 0 over Crystal Palace back in January. Since then The Blues have played out back-to-back 0 - 0 draws with Liverpool and Fulham before drawing 1 - 1 with West Ham. Then, most recently Potter’s side slumped to a 1 - 0 loss to bottom-of-the-table Southampton as well as a 1 - 0 loss away to Borussia Dortmund in the first leg of their Champions League Last 16 tie. This severe lack of wins and points leaves The Blues floundering in tenth place.
These two clubs have a lot of history with each other, playing 136 games against each other. Overall Chelsea have a better record winning 77 of the 136 games. Tottenham have won 55 of the encounters and both teams have left with a point just 42 times.
Players to watch this weekend could be Son for Tottenham and Joao Felix for Chelsea. Son had been suffering through somewhat of a goal drought recently, but that came to an end with his goal against West Ham, so the ruthless Son the Premier League is used to may make a return.
Though he didn’t make the best impression in his first-ever London derby, being sent off against Fulham on his Chelsea debut, Felix has looked like one of the few bright sparks at Chelsea as of late. The Portuguese also bagged his first Chelsea goal in another London derby against West Ham, so Felix could bring the flare to the Tottenham Hotspur Stadium.
