The holders will fancy their chances of reaching the last eight but this is by no means a straightforward assignment. Boro come in to this tie on the back of five successive league wins and buoyed by their stunning 2-0 win over Manchester City in the last round. Gabriel could make his debut at the back and Wojciech Szczesny will return in goal – with the Gunners the only side still fighting in the Cup and the Champions League, Arsène Wenger’s other changes will be interesting to see.
