Experience has proven crucial for both teams, with Xhaka and Henderson making a significant impact. Xhaka, 33, has been Sunderland's best player since their return to the Premier League, providing defensive solidity and scoring key assists. He has made 26 clearances and 20 aerial duels, and has a passing accuracy of 83.3%.

Xhaka's performance in the 1-0 win over Nottingham Forest was particularly impressive, where he won seven duels, made eight clearances, and provided the assist for the winning goal.

Henderson, 35, has brought leadership and stability to Brentford, filling the void left by Christian Nørgaard's departure. He has been praised by his teammates for his presence on and off the pitch, and has starred in big games against Chelsea and Manchester United, providing assists in both matches.

While both players have made a significant contribution to their teams, Xhaka's overall impact on the pitch has been more notable, making him a strong candidate for the signing of the season.
