Arsenal boss Mikel Arteta was thankful VAR was in operation for their 2-0 win over Newcastle in the FA Cup and praised the growing importance of Emile Smith Rowe. The 20-year-old proved the difference for the holders and grabbed the opener in the 109th minute after the tie had gone to extra time. It could have been a different ending for academy gradate Smith Rowe had the video assistant referee not told referee Chris Kavanagh to review a decision deep into stoppage time.
