'Arsenal need to spend big, sign Mbappe and keep Sanchez'

'The most important thing is to keep Sanchez and Ozil and if they buy Lacazette and Mbappe. Arsenal can do both, they can extend the contracts of Sanchez and Ozil and why not buy two or three players?', claimed the former Arsenal man.

'Kylian Mbappe is very good', said Pires, 'he is young, he needs to prove, he is only 18, but he is a great player, everybody knows. But, you know, Mbappe is very, very expensive!'.

The Frenchman believes that silverware is vital for Arsene Wenger's future at the club, and the manager must 'spend a lot of money' this summer: 'The first objective is to lift a trophy at the end of the season, if Arsene buys some players they can lift the Premier League trophy'.
