Arsenal 2, West Brom 0: Full time analysis
Mexican teenager Carlos Vela came off the bench to inspire Arsene Wenger's young Gunners to a 2-0 Carling Cup victory over 10-man West Brom at the Emirates Stadium.
The 19-year-old marked his return from an ankle injury when his shot set up Sanchez Watt for the opener in the 68th minute and then added a tap-in after Mark Randall's clever chip came back off the crossbar.
After a positive start the Coca-Cola Championship leaders were up against it after former Gunner Jerome Thomas - who twice won the FA Youth Cup while at Arsenal - was sent off after 37 minutes for a needless slap on Jack Wilshere.
Wenger had once again given youth a chance, his team with an average age of just over 20, while also bringing in experienced defender Philippe Senderos - starting for the first time since May 2008 after a loan spell at AC Milan - and veteran Mikael Silvestre captained the side.
Senderos - who could have joined Everton during the transfer window - had an early chance when he headed over at the near post following a corner from the left.

With Watt and French teenager Gilles Sunu Arsenal certainly had plenty of pace in attack, while Wilshere and Aaron Ramsey - both with plenty of first-team experience already - provided the trademark quick passing through the midfield.
Polish goalkeeper Wojciech Szczesny, 19, made the first meaningful contribution on his debut when punching a corner clear at the near post and he was stretching in the 15th minute as Robert Koren's angled 20-yard drive flew just wide.
Watt came within inches of opening his Arsenal account when he stabbed Wilshere's cutback goalwards, only for the ball to bounce agonisingly off the inside of the post and into Dean Kiely's grateful arms.
The match had suddenly sparked into life, West Brom midfielder Simon Cox the next to test Szczesny with a low drive.
The Pole produced another fine stop to turn Koren's shot behind, which was creeping in.
The youngsters were rattled - and Kerrea Gilbert hacked the ball off the line after a corner caused panic in the Arsenal six-yard box.
Arsenal responded well, with Wilshere again driving at the Baggies rearguard.
On 31 minutes, Wilshere again made space for himself with another positive run, and his 20-yard shot was just off-target.
