Arsenal have had a pretty decent week.After losing their first two Premier League matches since the return of football in England, the Gunners visited an in-form Southampton side and beat them 2-0 away from home.Then, on Sunday, they travelled to Sheffield United for their FA Cup quarter-final and came away with a 2-1 victory.The Gunners are on their way to Wembley.In truth, it wasn’t the greatest team performance with Nicolas Pepe giving Mikel Arteta’s side a first half lead with a penalty.But the home side appeared to be taking the tie into extra-time after David McGoldrick’s 87th-minute equaliser.However, Arsenal went up the other end and Dani Ceballos sent them through to the semi-finals.There were plenty of positives for Arsenal to take away from the match but the biggest was probably the performance of Kieran Tierney.p1ebu2h57n1ovcknn09s0oqrsg.jpgThe left-back, who arrived for £25 million from Celtic in the summer, has struggled with injuries throughout this campaign making just eight league appearances.But the Scot appears to be back.He produced a Man of the Match performance against Sheffield United as he showed Arsenal fans exactly what he’s about.He also showed off what kind of person he is when he arrived at Bramall Lane.Usually, you’ll see players step off the bus clutching a designer washbag full of their toiletries. But not Tierney.Instead, he Tesco bag for life will do the job.
