Motherwell boss Mark McGhee admits he still needs to strengthen his squad after yesterday's opening day SPL victory over St Mirren.
McGhee could not have asked for a better start when Steven McGarry swept home the opening goal just over two minutes into the game at Love Street.
Clarkson hit the bar soon after and Jim Paterson missed a penalty before Motherwell held on comfortably.
But McGhee feels he needs more players after they failed to keep up their sparkling early play.
He said: "I'm pleased with the points and pleased with the way we started the game. A second goal would have made it a bit easier.
"The second half was a little bit scrappy, which maybe demonstrates that we need a slightly stronger squad, a centre forward that can hold it up for us."
The former Wolves boss is also looking for a goalkeeper and left midfielder and is still considering a loan move for Celtic defender Adam Virgo.
