Former Liverpool defender Jamie Carragher believes that Arsenal should not rest on their laurels and strengthen their squad next season to challenge for the title.

The Gunners are on an eight-match winning run and face Chelsea at home on 26 April where the result will mean little in the title race, especially with Chelsea already 10 points ahead. A win for Jose Mourinho's men could see them pack the trophy three days later against Leicester City.

Mesut Ozil and Alexis Sanchez have shown glimpses of a blossoming partnership, which will only get better in the days to come, an ominous sign for other teams in the league.

However, Carragher believes that the current team is not up there to challenge Chelsea for the title and need better depth and quality between the posts, in defence, midfield and also in attack.

The Liverpool legend has urged Wenger to break the bank for Paul Pogba, who is reportedly available in the summer and also look to bring in Petr Cech and add another forward to complement his current set of players in attack.

"Results have been impressive since David Ospina replaced Wojciech Szczesny, who had failed to show the required consistency. Ospina has played 12 Premier League games; Arsenal have won 11 and he has kept six clean sheets, but Wenger still needs to buy a new No 1 if they are to be title challengers. Petr Cech would be an ideal candidate to come in," Carragher said in his column with the Daily Mail.

"Laurent Koscielny has steadied things in defence, with Arsenal winning 15 of the 18 games he's played since January 1 but, to progress, Wenger needs another top centre back. Gabriel Paulista arrived in the New Year but it seems it was to provide cover for Koscielny and Per Mertesacker.

"Francis Coquelin has added bite to the midfield, but would Arsenal have enough to challenge next season if Coquelin is their anchor and Mikel Arteta is his back up? No.

"Why doesn't he go for Paul Pogba, who looks set to leave Juventus? Wenger spent £42m on Mesut Ozil, so why not spend the same and more on Pogba. If they needed to sign Ozil two years ago, their need to sign Pogba this summer is even greater. Diego Godin of Atletico Madrid is 29 and at the peak of his powers. He would be ideal at the heart of the defence," he concluded.
