Jack Wilshere believes if Arsenal were to sign England team-mate Wayne Rooney it would strike fear into the hearts of their Barclays Premier League title rivals.Funds of more than £75million are understood to be available for manager Arsene Wenger as he aims to pull together a squad capable of mounting a long overdue sustained assault on the championship.Rooney asked to leave Manchester United at the end of last season but it remains to be seen how the situation will develop with the arrival of new manager David Moyes, his former boss at Everton.Speaking in a question and answer session with www.espnfc.com, Wilshere said: "If it happens, it would be amazing. He (Rooney) is the type of player who can win you trophies - and just to see his name on the team sheet brings fear to the opposition. We could do with a little more of that."The Gunners are set to be busy in the summer transfer window, with the confirmation of the free transfer of France Under-21 attacker Yaya Sanogo set to be shortly confirmed now his contract with Auxerre has expired.Arsenal have also been linked with Real Madrid's £25million-rated forward Gonzalo Higuain and Everton midfielder Marouane Fellaini, who would, like Rooney, both command significant wages.
