Cahill's Millwall move: 4 burning questions

Tim Cahill's club future has been settled with a return to his first professional club Millwall confirmed for the remainder of the Championship season in England.

After leaving Hyundai A-League club Melbourne City in December, Cahill will now look to get as much game time as possible as he aims to go to a fourth FIFA World Cup with the Caltex Socceroos.

The 38-year-old seemingly had options to play anywhere in the world but decided to return to the club where his career really got going two decades ago.

But is a return to England the right move? We answer some of the burning questions below.

HOW MANY GAMES COULD HE PLAY?

There's 18 games left in the Championship season - plus any extra FA Cup games - beginning with Wednesday morning's clash with second-placed Derby County at The Den.

Throw in the two Caltex Socceroos friendlies against Norway and Colombia in March and Australia's greatest ever scorer could get plenty of game time before heading to Russia.

HOW ARE MILLWALL TRAVELLING?

After gaining promotion from League One last season, the Lions have made a good fist of their return to England's second-tier competition.

Neil Harris' side sit 15th after 28 games, nine points above the relegation zone.

Their relatively healthy position has been built on their home form, with 25 of their 34 points coming at The Den.

Barring a complete drop in form, Millwall should do enough to avoid falling into a relegation dogfight in the coming months.

WHO COULD HE COME UP AGAINST?

Cahill should feel right at home in the Championship, with a stack of Aussies currently playing in the league.

As well as having James Meredith as a teammate, Cahill will take on Jackson Irvine's Hull City, Bailey Wright's Bristol City and Mile Jedinak's Aston Villa before the end of the season.

The clash against Villa will also see Cahill go up against former England captain John Terry, who marshals their defence.

There's also a number of Danish players in the Championship that are likely to face Cahill at the FIFA World Cup, including Middlesbrough striker Martin Braithwaite, Brentford defender Andreas Bjelland and Ipswich's Jonas Knudsen.

WHERE COULD HE FIT IN?

While he started his career at Millwall as an all-action midfielder, in recent years Cahill has been used predominantly as a striker.

Millwall have a number of options in attack.

Young Irish attacker Aiden O'Brien has been in consistent form all season, while Englishman Lee Gregory is the team's leading scorer.

There's also club legend, 34-year-old Steve Morison, still at the club and getting amongst the goals.
