Gary Lineker believes Olivier Giroud could be set for a prolonged spell as an Arsenal substitute.

The 30-year-old came off the bench to provide an impressive assist for Alexis Sanchez to score his second during injury time in the Gunners’ 3-1 triumph over Bournemouth on Sunday.

Match of the Day host Lineker claimed on his personal Twitter account that Giroud’s eye-catching displays as a substitute could mean that he may only be used in that role by manager Arsene Wenger.

Arsenal’s number 12 has earned the reputation of a super-sub after scoring against Manchester United and Sunderland despite not starting.

The former Montpellier striker has failed to start a Premier League match this season, with Alexis Sanchez being preferred to Giroud in the spearhead role for Wenger’s side.

Sections of fans had called for Giroud be given a chance from the off against Bournemouth, but he has instead been to made to wait by Wenger for his first Premier League start of the season.

Chilean Sanchez scored a brace for the Gunners, meaning he is unlikely to be dropped in favour of the France international for next week’s league clash against West Ham.

However, Giroud could be given a chance in Wenger’s starting XI on Tuesday night as the Gunners look to book their place in the semi finals of the EFL Cup against Southampton.

The win against Bournemouth sees the Gunners consolidate their position in fourth place, by going four points clear of North London rivals Tottenham who sit in fifth.
