Arsenal sign wonderkid Campbell

Arsenal have won the race to sign Costa Rican wonderkid Joel Campbell, according to The Sun.

The Gunners' £900,000 bid for the striker, 19, was accepted by Deportivo Saprissa last month.

But the move broke down when he refused to make a decision until after the Under-20 World Cup in Colombia.

The starlet reopened talks with Arsenal last week, though, and a source close to him claims a deal has been done

Meanwhile, the tabloid also reported that Arsene Wenger admits he is having sleepless nights as Arsenal's season threatens to go into meltdown - before it has even started.

Wenger said: "I would have preferred to finish in the transfer market but it does not work like that.

"We have had some sleepless nights and we were working non-stop through the summer.

"The injuries are making things difficult. We start the season next week and then we have a Champions League qualifier.

"We need to qualify and hopefully we won't have any more injuries from the international matches. We could be hit hard if we lose any more.

After next Saturday's opening Premier League match at Newcastle is the first leg of the Champions League clash with Udinese, who were fourth in Serie A and boast Italian football's top-scorer for the last two years, Antonio Di Natale.

Stoke target Nicklas Bendtner and Emmanuel Eboue, wanted by Galatasaray, have stayed behind in England.

Wenger is confident of new faces with Southampton's Alex Oxlade-Chamberlain likely to be arriving next week.
