Gabriel Martinelli has suggested that Arsenal needs to strengthen their attack this summer and welcomes the competition for places that any new arrivals would bring.

Sources have informed ESPN that Arsenal will seek a striker at the end of the season and might also pursue a winger, with Athletic Club's Nico Williams among their top targets.

Arsenal will face Paris Saint-Germain in the first leg of the Champions League semifinal on Tuesday, aiming to win Europe's premier club competition for the first time in their history.

The Gunners failed to win the Premier League title and are on track to finish second for the third straight campaign, having scored 17 goals fewer than champions Liverpool.

Mikel Arteta is focusing on enhancements in the final third, and when asked if speculation has added pressure, Martinelli said: "We play for Arsenal -- it's a competition every day.

"The club wants to have the best players in the world, because it is one of the biggest in the world as well. We are used to it."

When pressed on whether the club needs attacking reinforcements, Martinelli replied: "We are a big club. We need to have the best players. I will be really happy when we have big players coming to the team."

Martinelli has two years left on his current contract, having originally joined the club in a £7 million deal from Brazilian club Ituano in July 2019.

"I always said that I am really happy here," he said. "This is my home. I love to be here. I love the club.

"The club has given me so much, not just on the pitch, but off the pitch as well. I have improved a lot with the club -- of course, on the pitch is important, but off the pitch as well.

"The club has been amazing with me, the people around the club, the fans, everything. I am really happy here."

Arsenal has reached the Champions League semifinals for only the third time in their history, and Martinelli admitted that Tuesday's match is the biggest game of his life.

"It's a dream to be here," said Martinelli. "Since I started playing football at five or six, I had this dream to play in the Champions League, and reaching the semifinal is amazing.

"Everyone who loves football would love to play in these kinds of games. Everyone has to have their dreams. You dream to try to make it real."
