Arteta hails 'huge boost' as Arsenal reach CL semis - but problems remain

Mikel Arteta says reaching the semi-finals of the Champions League is a 'massive boost' for Arsenal despite once again struggling against Sporting on Wednesday.

The Gunners held on for a 0-0 home draw in the second leg of their quarter-final tie, meaning Kai Havertz's lone goal in Lisbon was enough to book them a place in the last four.
