Arsenal responded to their dismal start to the Premier League season on

Tuesday by signing South Korean striker Park Chu-young and German

defender Per Mertesacker on the penultimate day of the transfer window.

Manchester City meanwhile was linked with the surprise capture of injury-plagued midfielder Owen Hargreaves.

Some

$US600 million ($A560 million) has already been spent by Premier League

clubs since the end of last season, a figure set to rise even higher as

the final transfers before January are completed by 0800 AEST on

Thursday.

Arsenal has been under the greatest pressure from their

fans to bolster their squad after seeing almost $US100 million ($A94

million) come in for midfielders Cesc Fabregas and Samir Nasri this

month.

Now manager Arsene Wenger is starting to spend some of it

after Arsenal collected just one point from their first three league

matches, with Sunday’s 8-2 rout by Manchester United the most goals

conceded by the team since 1896.

The first of several expected

deals to be completed was Park, the South Korea captain moving to north

London after three seasons with Monaco.

Werder Bremen general manager Klaus Allofs has also confirmed the transfer of Germany defender Per Mertesacker to Arsenal.

An official announcement is expected on Wednesday, following the completion of some final details between the clubs.

German

media says Arsenal will pay around 10 million euro ($A13.6 million) for

the central defender who is entering the final year of his contract

with Bremen. The 26-year-old Mertesacker will reportedly receive a

contract until 2015.

Wenger is also trying to further strengthen the defence with Brazilian left back Andre Santos.

If

the 28-year-old Santos leaves Fenerbahce, he will help fill the void

left by the departure of Gael Clichy to Manchester City and Armand

Traore to Queens Park Rangers.

Big-spending City has been one of

the busiest clubs again this summer as Roberto Mancini spends Abu Dhabi

owner Sheikh Mansour’s cash on talent including Sergio Aguero and Nasri.

The

club’s biggest gamble could be about to be made by signing Hargreaves,

who was released by Manchester United after four injury-restricted

seasons.

Surgery on both knees restricted the 30-year-old former Bayern Munich player to just four appearances in the last three years.

The

former England international was unable to find a club before the

season started and posted videos on YouTube to prove his fitness.

But on Tuesday, Hargreaves was pictured going into a Manchester hospital for a City medical examination.

“He

hasn’t played as much as he would have liked over the last couple of

seasons but the medical team we have is very good and very strong. If we

can get him fit, I’m sure it won’t be very long before he is back to

his best,” said City defender Joleon Lescott.

City shares the Premier League lead with Manchester United after thrashing Tottenham 5-1 on Sunday.

It

was a result that exposed Tottenham’s shortcomings and now the club is

finalising the signing of England midfielder Scott Parker after he

handed in a transfer request at West Ham.

Liverpool has completed

the $US11.5 million ($A10.79 million) signing of Uruguay defender

Sebastian Coates from Nacional de Montevideo, according to international

– and now Anfield – teammate Luis Suarez.

Kenny Dalglish had

already shored up Liverpool’s defence by signing Jose Enrique from

Newcastle and the north east club signed a replacement No.3 on Tuesday

with Italy defender Davide Santon joining from Inter Milan penning a

five-year deal.

Elsewhere, Wigan signed 29-year-old Spanish

winger Albert Crusat from Almeria on a two-year contract and German

goalkeeper Gerhard Tremmel, 32, joined Swansea on a two-year contract

after being a free agent since leaving Austrian club Red Bull Salzburg.
