Alex Oxlade-Chamberlain is the son of former England International Mark Chamberlain. He was born August 15th 1993. Chamberlain made his senior debut for Southampton as a late substitute with the team 5-0 up at home to Huddersfield on March 2nd 2010. Chamberlain had a chance to make himself an instant hero, but missed a one on one with the Terrier's goal keeper. Despite that miss, Chamberlain became the second youngest player to play for the club, behind only Theo Walcott. He appeared one other time that season, as a substitute in the final match of the season against Southend.
Chamberlain played in most of Saints pre season games for the 2010/11 season without looking particularly spectacular. He scored his first goal for the club in his first competitive start, a 2-0 victory in the League Cup against Bournemouth. Chamberlain made a big impact in the 2-1 win against Oldham in October, changing the whole complexion of the game and grabbing the winner. Shortly after that he gave Dagenham & Redbridge a torrid time, scoring two fantastic goals helping the team to a 4-0 win. By this time he had replaced Jason Puncheon as an automatic starter
As Chamberlain put in more dazzling performances after Christmas and into the New Year, some of the big clubs started to take note. Liverpool Sporting Director Damien Comolli and Kenny Dalglish were spotted at a few Saints games, believed to be watching Chamberlain. Arsenal and Tottenham also had him watched, while Sir Alex Ferguson was in the stands at Oldham to see him notch the first goal in a 6-0 hammering. Despite much speculation, including some reports which suggested a move to Arsenal was a done deal, Chamberlain remained a Southampton player. His performances dipped slightly during this time, partly due to opponents taking extra precaution with the teenager and partly through burnout.
Chamberlain made his England under 21 debut on 8th February in a 0-0 draw against Italy. The young midfielder returned to form in March, and scored in consecutive games against Colchester and Yeovil. He hobbled off injured at Charlton on March 21st, and was forced to sit out Southampton's promotion run in. Alex was named in the 2010/11 League 1 team of the season on April 17th. He returned to action on the final day of the campaign against Walsall on May 7th 2011, where hit the post seconds after coming on. Chamberlain made amends minutes later though, by netting a long range screamer in a 3-1 win.
In July 2011 Chamberlain was fined by Southampton for giving interviews to The Mirror and The Sun in which he stated his desire to leave the club for the Premier League. He was finally granted his wish on 8th August 2011 when he signed a long term contract with Arsenal. According to the Press Association, the deal was worth £12,000,000 up front, plus add ons which could eventually take the transfer to £15,000,000. After a few appearances as an unused substitute, Chamberlain made his Gunners debut on 28th August 2011 in an 8-2 defeat at Manchester United
Chamberlain put in two eye-catching displays for England U21’s in September 2011. On 1st September he put in a brilliant performance, linking up with Liverpool’s Jon Flanagan on the right, and also setting up two goals in a 6-0 win over Azerbaijan. He performed even better four days later against Israel, putting in assists for all of England’s goals in a 4-1 win over Israel. Chamberlain scored in his first full start for Arsenal on 20th September in a 3-1 Carling Cup win over Shrewsbury. 8 days later he became the youngest English player to score in the Champions League, netting in a 2-1 win over Olympiakos. Chamberlain scored a hatrick for England U21's in a 3-0 win over Iceland on October 6th 2011.
Chamberlain quickly became a fans favourite at Ashburton Grove, appearing sporadically in the Arsenal side throughout 2011/12. He made a real impact on 22nd January in a 2-1 home defeat to Manchester United. When he was substituted for Andrei Arshavin on 74 minutes Arsenal fans booed in disgust. He scored twice in a 7-1 win over Blackburn on February 4th 2012. Chamberlain continued to look promising later in the campaign, and won praise from the great Marco Van Basten after a stunning showing against AC Milan in the Champions League on 6th March 2012.
On 16th May 2012 it was announced Chamberlain would be included in Roy Hodgson’s 23 man England squad for Euro 2012.
