The French international left the Premier League last summer,
quitting Arsenal to move to Catalan giants Barcelona.
But despite still being in with a chance of winning the league and
Champions League this season, Henry is still not thought to have
settled well in Spain.
It's not known whether the former Gunner is angling for a move back
to English football, but either way, Keegan says it's definitely an
option worth investigating.
"I would like to fetch Thierry Henry back to England," Keegan
told Radio Newcastle. "He's the best player I've seen in the
Premiership. When you're pitch-side, what I've seen him do to good
players has been incredible. Sometimes you can take advantage of a
situation and get what I call lucky.
Keegan is no stranger to big-name transfers: as manager of
Newcastle United in 1996 he spent a then-world record £15m to bring
Alan Shearer in from Blackburn Rovers. And if the money is
available again, Keegan says he has no problem with setting new
landmarks.
"I'd like to do what we did last time and surprise people. It would
be nice to break a world record," he said. "Why rule it out? I'd
like to bring players here that amaze people and we stop just
talking about being a big club - but, with our actions, we show
that we are. Sometimes people limit themselves by saying, 'we can't
do that'. You say 'why not?' and they don't give you an
answer.
"If we can get this club going in the right direction we have the
owner who will find us the money for these players. You start by
building up trust with the people who provide the finance that you
can find these players at the right price. It's easy to get players
to a club once it's flying in the right direction."
